GnuTLS error -8: A packet with illegal or unsupported version was received.

I have two VMs set up using the same version of FileZilla Server (0.9.13b). On ServerA I seem to have no issues when connecting with TLS. On ServerB (a new one I have created) I have an issue connecting using the same client with the same settings…
GnuTLS error -8: A packet with illegal or unsupported version was received.
Is there something I need to do on the server itself to support other TLS versions like TLS 1.2?

You absolutely must update those servers. Cheesus fucking crust that’s antique….

LOL I’m trying to but there were features taking out of the newer versions that are no longer available to me in the newer versions. I would love to update so bad. But as old as that version is and as much as I would like to update it, the issue I’m experiencing is not related to the age of the version of Filezilla server I’m running. Like I said, it works fine with no issues on another server. I’m just trying to figure out what is different on the Windows Server 2019 boxes that would allow one to use TLS 1.2 and one to only use TLS 1.0.

To ask a more pointed question…
FileZilla Server 0.9.13b beta does support TLS 1.2 correct?

Thanks boco! Then at this point I’m really confused. LOL
I have 0.9.13b beta running on a server and I have the latest version of FileZilla Client running with minimum version of TLS 1.2 required. It connects with no issues. How is that possible?
On the left is FileZilla Client FTP log (with detailed info) and on the right is the settings from FileZilla Client.
Running these same settings connecting to the second FTP server that should be 100% identical to the first (production and working as seen above) with the exception that the second (non-working) server is on a domain.

That old version does not officially and properly support TLS 1.2. However, I guess it makes no attempt to limit the upper TLS version, if the underlying OpenSSL library supports it (even if only experimental). Therefore, it negotiates whatever is supported by OpenSSL.
However, that doesn’t mean it will support any of the security features of TLS 1.2 properly. Plus, it comes with a truckload of security vulnerabilities that will make grown men cry.
Official, proper TLS 1.2 awareness came with 0.9.43.

Unfortunately it looks like it might be time for me to move on from FileZilla Server. There was a small feature that is available in that «old version» (0.9.13b beta) that we have to have. In later versions the feature is now being actively blocked (for now reason other than it was not considered to ever be used by botg in the past). I have requested that this feature not be blocked and allowed but have not really heard any type of acknowledgement that it would be allowed again in the current version.
Anyway, as much as I love the FileZilla dev team and the product because of this I’m having to look for other solutions free/paid that will work for me. Thanks guys!

I realize that this is an ancient topic but I am seeing these errors in the log of the latest version:
Code: Select all
GnuTLS error -8: A packet with illegal or unsupported version was received.Are they anything to be concerned of?

It’s either antique clients or random garbage.

Are you seeing the following error in your FileZilla FTP client? If so, I have the solution for you.
Status: Connection established, waiting for welcome message…
Status: Initializing TLS…
Status: Verifying certificate…
Status: TLS connection established.
Status: Logged in
Status: Starting download of /domains/taskini/.htaccess
Status: File transfer successful, transferred 260 bytes in 1 second
Status: Disconnected from server
Response: 421 Timeout — try typing a little faster next time
Error: GnuTLS error -110 in gnutls_record_recv: The TLS connection was non-properly terminated.
Response: 421 Timeout — try typing a little faster next time
Error: GnuTLS error -8: A packet with illegal or unsuported version was received
Status: Connection attempt failed with «ECONNABORTED» — Connection aborted
Error: Disconnected from server
This is what happened to me. Last week, I opened the FileZilla FTP client to connect to a customer’s website and it prompted me to upgrade. I did my work and upgraded after I was done.
The following week, I tried to connect to my server and I couldn’t I kept getting an errors:
Error: GnuTLS error -8: A packet with illegal or unsuported version was received
Status: Connection attempt failed with «ECONNABORTED» — Connection aborted
Error: Disconnected from server
The solution:
I downgraded from Version FileZilla_3.56.2_win64-setup.exe to FileZilla_3.55.1_win64-setup.exe
Now it works. Hope that helps.
If while trying to login to your FTP account via the popular FTP client Filezilla to our legacy hosting environment and you receive the following error,
Error: GnuTLS error -8: A packet with illegal or unsupported version was received.
Status: Connection attempt failed with "ECONNABORTED - Connection aborted".
Error: Could not connect to server
You can fix this with a slight change to your connection settings:
- Click Edit
- Settings
- Connection
- Under TLS options, set this to TLS 1.0
You should now be able to connect without the error.

You will be informed via email, as soon as your order items are available for
download on the FTP Delivery Server. The email will contain the
address of the FTP Delivery Server and the path to the data packages.
Also, FTP address and path are available in the order overview.
Note
The user ID and password to access the FTP server are identical to your
EOWEB® GeoPortal (EGP) user ID and password.
Note
Delivery packages are deleted from the delivery server
15 days after insertion.
Please make sure to pick up your products in time.
Due to security regulations the ordered products have to be delivered via FTPS.
The FTP clients used for downloading must support the SSL/TLS encryption.
Plain FTP clients (including Internet Explorer) won’t work!
At least the following clients support FTPS:
Windows:
- FileZilla (recommended, free, Version 3.1.3.1 or later)
- FTP Voyager Secure Version 9.0.0.7
- Smartftp 1.0.968.0
- CuteFTP Pro
- Secure FTP 1.6
- Igloo FTP Pro
- FlashFXP 2.0
- WS_FTP Pro Version 7.5T
Unix/Linux:
- FileZilla (recommended, free, Version 3.1.3.1 or later)
- lftp
- Secure FTP 1.6
- Curl7.15.2
- Igloo FTP Pro
- Incredible FTPS
- Kasablanca FTP
The client has to be set to “passive mode”, as the FTP server
assigns the ports used for the data transfer.
The connection port is 21.
The range of passive ports is between 30000 and 30300.
It must be ensured that the firewall settings do not block these ports which most firewalls do
(although your firewall might allow outgoing FTP transfers, it migt block FTPS because it can not
decrypt the data package which would tell it that these are FTP data connections)!
Example for FTPS settings¶
Here you can see a screenshot of FTPS settings in FileZilla:
Troubleshooting¶
| Problem | Solution |
| Login is not possible even though using the correct login-id and password (550 SSL/TLS required on the control channel): |
|
|
Switch to TLS Version v1.0, v1.1 or v1.2 |
| Login is possible, client supports FTPS, file list is not provided: | firewall is blocking the passive ports, open the passive ports 30000 to 30300! |
| Client supports FTPS, login is possible, connection is interrupted with the message “500 illegal PORT command“ | Please switch to “passive mode” |
