Can anyone tell me if this is strictly a server issue. I have been with our IT Dept and they are saying no, the Vender in which I use this software to remote is saying yes. Help!!!! :( This is the new version downloaded Jan2015, using windows 7

Most likely a server issue. Unfortunately the hostname has been removed from the log so I can’t analyze this further.

I had a simillar issue.

Turned out that the client was outdated.
did not work with Filezilla 3.6.0.3 & GnuTLS 3.1.4, but worked fine with Filezilla 3.7.4.1 and gnuTLS 3.1.11.

Speaking of outdated, that too are heavily outdated versions.

I’m using FileZilla 3.10.0.2 with GnuTLS 3.2.20 (current, if I’m not mistaken) and I’m getting the same error (which has for quite some time forced me to use CoreFTP instead of FileZilla to connect to this server):

Status: Connecting to 208.75.145.17:990…
Status: Connection established, initializing TLS…
Error: GnuTLS error -110: The TLS connection was non-properly terminated.
Status: Server did not properly shut down TLS connection
Error: Could not connect to server

Is that enough information to diagnose the problem?

Thanks!

@alexander.oss: Your server does not seem to support strong cryptography, it only seems to support deprecated and insecure algorithms.

I installed a FileZilla update this morning. Now I cannot log in and am getting the above error.

I seem to have version 3.10.1.1 (c) 2004-2015
this version seems to have been built 02/01/2015

wxWidgets: 3.0.3
GnuTLS: 3.2.21
SQLite: 3.8.8.2

I run Windows 7 64-bit system

I have completely uninstalled & re-installed FileZilla in an effort to resolve.

I do not have on-site IT support as we are a very small business. I’m not sure what my next steps should be.

I have the same versions and builds as rachaelinsall and is getting the same errors.
One thing worth noting is that is has been working fine at home, but now two days later I am on a different network (hotel) connecting to the same server.
I can upload files using CPanel, but that is a single file at a time.

ANY setting I can change to bypass whatever prevents me to use FileZilla with default settings?

Do you really want to give up on security in a public network? Then set the Encryption for your server entry in Site Manager back to Plain FTP.

While setting the connection to plain FTP does work, this is not a good idea. Also, since this seems to be a wide spread issue on many servers, where the client is using filezilla, where other clients work fine, I believe this is a problem with filezilla, and not a server side issue.

i have exactly the same issue on a cPanel enabled server where I have root access. The server is using Pure-FTPD (default for cPanel servers)

This happens with file transfers, using filezilla 3.11.0.2

Since this FTP server is the default for cPanel servers, and this problem is wide spread, perhaps this should be seen as a bug in the filezilla client.

Just my 2 cents

It has been explained multiple times why it is a problem with the servers and not with FileZilla, but here, again:

FileZilla asks if FTP over TLS is supported. The server replies: Yes. Then, FileZilla actually attempts to use FTP over TLS and the server craps out, because it is not properly configured despite saying so.

Solution: The server should either properly support FTP over TLS, or tell FileZilla that it doesn’t support it (by denying the AUTH command).

boco, I do belive you are right. It is not a problem with Filezilla but with the servers. However, given that many many servers are still not configured the proper way as for example intranet FTP servers which may not have had that requirement before or simply because of a lack of proper configuration, I think a better explanation is deserved.

The fact is that with previous versions of Filezilla, the default Encryption type for sites was «Plain FTP». All my sites were set this way. I’ve recently updated my Filezilla from 3.5.1 to 3.10.3 and I started to get the error we are talking about here. Of course, I did not notice that change in the default Encryption setting after the update. After some googling, I found out that the error has been caused by Filezilla’s new version which has now changed it’s default Encryption type to «Use explicit FTP over TLS if available». This change has been automatically applied to all the sites under our Site Manager. It is not a bug with Filezilla. It’s just that Filezilla has decided to implement this ahead of everyone else I believe. I’ve tried other clients and the default «FTP over TLS» is not attached to sites by default. It is still «Plain FTP» so all sites are connecting as expected. This is probably the reason why several users are blaming Filezilla rather than pinpoint the real issue.

Despite the fact that it is a very good approach to strenghten the security by default, several users (including myself) who upgraded with a more recent version of Filezilla were faced with this error for each and every site we were trying to connect to since some or all of our sites were previously set to connect by default with Encryption set to «Plain FTP». I’m in a large corporation (30 000 employees) and have no access to any of the FTP servers we are hitting because they are supported by another department. So, I need to switch back the Encryption settings to «Plain FTP» for all my sites. So be it… Because as you can imagine, I cannot request a nation-wide change to be applied to our numerous servers because Filezilla said so.

Therefore, I do believe that some of us here in this post are trying to figure out why this is happening and unfortunately all the evidences are pointing to Filezilla as the source of the problem which is not true. Clarifications are required which you did not mind posting…

I’m no big fan of your type of support since you seem to prefer to be rude rather than actually give better and constructive explanations. This is not acceptable in my opinion. Nevertheless, I still find that Filezilla is a very good product.

I do not know what your perception of ‘rude’ is, but if you mean the fact that we won’t spoon-feed everyone, you’re right.

We do not have the time to do individual customer care. At the same time, the target audience for FileZilla are advanced users. So we expect users to at least read a little and search for their problem before asking the same questions that have been answered already hundreds of times. There’s the FAQ and the Wiki, for exactly that reason.

tl;dr: «Customer Care» and «Technical Support» are different things. Tech-support sounds harsh often because there’s no mincing words with icing on top. :D

boco, if you are assuming that your target audience is advanced users, you missed your target. Not sure if you read the subject but to my understanding, it says: «GnuTLS error -110: The TLS connection was non-properly terminated». I’ve searched the FAQ and Wiki and haven’t found any reference to this error. According to the first replies to this post, even botg was not even clear on what was going on:

Most likely a server issue. Unfortunately the hostname has been removed from the log so I can’t analyze this further

and you are assuming that everyone should be able to figure this out themselves? When a massive load of users are asking the same question here and there, how hard is it to post a link explaining why this happens and how this can be resolved?

Since you don’t seem to «care» or «support» much, I will post a «bug report» right here for users who are looking for some kind of «explanation» of the source of the problem. This should show you how smoothly «advanced users» were able to handle this. It will also show you the users how convinced Filezilla guys are that everyone in the world should follow Filezilla’s new feature when they release it. Because when Filezilla makes a change, it becomes officially the new internationally approved standard, right?

Ticket 9995 is a good example how users disregard objective facts presented by an expert on the topic.

Instead of addressing the root of the problem these users instead want to shoot the messenger.

They keep arguing and arguing the same uninformed nonsense, constantly attempting to shift blame away from cause the problem and instead towards the trigger of the symptoms.

They don’t understand the problem and actively refuse to learn new things. On top of it they reject whatever those that do understand the problem have to say.

I think there’s a fitting quote for this kind of situation:

Isaac Asimov wrote:Anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that ‘my ignorance is just as good as your knowledge.’


I observed that one of my Windows Services was not connecting to an FTP location on a Unix Server, I ran the executable on my PC as the dev didn’t log any error and i was getting timeout error on trying to get response from an FTPWebRequest Object in C#.

On trying to access the FTP location using Filezilla I am getting the error

GnuTLS error -110: The TLS connection was non-properly terminated.

Using SFTP does not give this error and also using FTP in plain text(insecure) also does not.

I really do not understand this and note that the application has been running fine for years and this just suddenly happens on like 4 servers.

GnuTLS error -110: The TLS connection was non-properly terminated.

That just means that the peer just closed the socket and did not do a proper TLS shutdown. Some broken clients or servers do this. Assuming that this message relates to a data transfer you can usually ignore this because the transfer was finished anyway, so no data got lost.

Using SFTP does not give this error and also using FTP in plain text(insecure) also does not.

Of course you don’t get it, since SFTP is using the SSH protocol instead of TLS and plain FTP does no encryption at all, so no TLS too. And if there is no TLS involved you can not get any TLS errors.

I really do not understand this and note that the application has been running fine for years and this just suddenly happens on like 4 servers.

It might simply be that the servers changed, i.e. either they never supported FTPS (i.e. FTP with TLS, not to be confused with SFTP) before or they now switched to a broken implementation.

If you are connecting to a cPanel server then you can temporarily fix this issue by enabling «Broken Client Compatibility» in Pure-FTP settings in WHM.

Older version of Filezilla may be responsible for the said error. Faced the same error on 3.4 version issue was resolved after downloading the 3.6 one.

Получилось решить проблему только переключением способа шифрования — вместо «Использовать явный FTP через TLS если доступен» ставлю «Использовать обычный FTP (небезопасно)».

I am trying to download some files from a server using FileZilla 3.9.0.5, using regular FTP over explicit TLS. Many files download just fine. It refuses to download certain files, however, giving me messages like the following:

Status: Starting download of /public_html/foo/bar/baz.php
Command:    PASV
Response:   227 Entering Passive Mode (***my server IP***)
Command:    RETR baz.php
Response:   150-Accepted data connection
Response:   150 13.0 kbytes to download
Error:  GnuTLS error -110 in gnutls_record_recv: The TLS connection was non-properly terminated.
Status: Server did not properly shut down TLS connection
Error:  Could not read from transfer socket: ECONNABORTED - Connection aborted
Response:   226-File successfully transferred
Response:   226 0.000 seconds (measured here), 26.04 Mbytes per second
Error:  File transfer failed after transferring 13,653 bytes in 1 second

The server in question is a CentOS/cPanel box.

Can someone tell me how to resolve this?

EDIT: Some additional insight: the files on which FileZilla melted down had some hard tabs (character 9). I replaced all hard tabs with 4 spaces in the copies of these files on the server, then was able to download them just fine. Maybe something about the tab characters caused the problem?

EDIT 2: The server logs just have lots of entries like this:

Sat Sep 13 18:24:26 2014 0 ****** 13682 /home/******/public_html/foo/bar/baz.php a _ o r ****** ftp 1 * c

The ******s above represent the IP, username, and username again for the account in question. Except for the time stamp and number of bytes transferred, the entries for failed transfers are identical to the successful ones.
