Ошибка openvpn exited with error exit code 1

Hello!

I couldn’t find any reference to this particular issue online, so more than likely it’s something simple I’m overlooking; however I haven’t found what the issue is as of yet and so I come here for help.

I currently have a few laptops I set up for people using OpenVPN GUI in Windows. When connecting from the GUI, a user will get an error messaging saying it couldn’t connect to the management interface and to check the logs. This happens intermittently.

The logs only have «Enter management password: «

The only way around this (other than rebooting) is to restart the Interactive Service.

I recall reading somewhere on openvpn.net where this issue is caused by the connection profile being started already and it’s commonly caused by the OpenVPN Service and OpenVPN Legacy Service being used at the same time; however, I observed that only openvpn-gui.exe was running when this happened. The OpenVPN Service and OpenVPN Legacy Service (both set to manual) were not running.

The version of the OpenVPN Client being used is 2.4.6. I tried 2.4.7 to no avail.

If I check the event logs I see an Error entry under Application logs for openvpnserv but it only says:

The description for Event ID ‘0’ in Source ‘openvpnserv’ cannot be found. The local computer may not have the necessary registry information or
message DLL files to display the message, or you may not have permission to access them. The following information is part of the event:’openvpn
serv error: ‘, ‘0x20000000
OpenVPN exited with error: exit code = 1

I’m at a loss as to what causes this. Right now I’m attempting a workaround with a scheduled task to restart the Interactive Service triggered by a custom event filter with the aforementioned event log entry.

I’ve witnessed this happening on Windows 7, 8.1, and 10.

Thoughts?

Topic: Не подключаеться!

Здравствуйте, у меня выбивает ошибка когда нажимаю на подключиться.

Что в начале пишет:
Fri May 05 17:34:36 2017 OpenVPN GUI>OpenVPN terminated with exit code 1. See the log file for detail

Потом вылазит окно и в самом окне пишет:
Не удалось подключиться к Russia_freeopenvpn_udp.

Использовали сначало Нидерланды. Потом и с ними выбивало тоже самое, изменили в конфиге файл.
Дальше выбивает, жду ответа.

P.S. Очищал так-же КэшDNS.
Спасибо заранее!

GUI Tray Icon dissapears after laptop sleep/unsleep action Windows 10 #276

I found that almost every time when I close lid of my laptop, I don’t find GUI tray icon anymore to connect/disconnect any connections.

After that I should close OpenVPN daemons with taskmanager, start Openvpn GUI again, and reconnect all connections I need. Do you have any ideas how to solve it?

The text was updated successfully, but these errors were encountered:

Have you checked the config of «visibility options for icons in the notification area» ? Does the GUI program actually die?

yes right now visibility set to always show, and issue still exists. So when I open laptop after sleep, it disappear in 2-3 seconds, and I don’t see it in processes, but connections still running fine.

But I start it again as admin or as user, I can’t connect to my connections any more and they marked as not active

and seems I have this log in windows event viewer

The error you get is expected if the connection is active and you are trying to start another instance possibly using the same log file and same tap adapter. Instead, you will have to manually kill any running openvpn process(es) before attempting a restart. Just as you posted on Aug 5.

But the real question is why the GUI is abnormally terminating on suspend. I have not seen it before but can try to reproduce given more details: Windows version, GUI and openvpn versions, and verb = 4 log file of the openvpn process that remains active after the resume. Does a clean reinstall help? — by clean I mean uninistall and clear the HKCU/Software/OpenVPN-GUI registry key. Note that will also delete any saved encrypted password blobs.

Ok I will try reinstall, enable verb 4 logs and will back to you.

As for now, I’am starting GUI autoconnect with Task Scheduler at system logon C:Program FilesOpenVPNbinopenvpn-gui.exe —connect dev.ovpn

Maybe it’s the reasons of these crashes? Maybe there is some other Official way to autoconnect with gui on system startup?

By «at system logon» if you mean on bootup before any user has logged in, that will definitely not work. With proper flags (interactive, run only when user is logged on etc.) it should work, though I haven’t tried.

Anyway try first by adding the GUI to the startup menu (see settings) to automatically start the GUI on logon and then manually start the connection. If that works without issues you know where the problem lies. For auto connect making a shortcut with —connect dev.ovpn as the argument and adding that to launch on logon may be better than using task scheduler.

I used this one

but will try all your suggestions, and return back to you

This may not fix your problem, but do not run the GUI with «highest privileges» — just run with the usual limited privileges. That is how GUI shipped with 2.4 is supposed to be used.

Problem solved after moving startup to shell:startup shortcut. So it seems was some Task Scheduler issue. Thank you for your help!

Fedora clients can’t start openvpn on boot

Fedora clients can’t start openvpn on boot

Post by Chrismur91 » Wed Oct 17, 2018 3:12 pm

I have a couple of new machines with Fedora 28 installed that I’m trying to configure to connect to our VPN server. I can get the clients to connect successfully by manually entering openvpn —config client.conf, but I can’t get the connection to start on boot.

I’ve spent some time troubleshooting and researching, but I’ve come up empty on a solution.

Some quick notes to eliminate certain troubleshooting:
— The client.conf file is located in /etc/openvpn
— The client.conf file permissions are set to 400
— The client certificates are located in /etc/openvpn/client

After some research I found that I may need to specify the client file when starting the service, so I tried this:
systemctl start openvpn-client@client
and I receive the following:
Job for openvpn-client@client.service failed because the control process exited with error code.
See «systemctl status openvpn-client@client.service» and «journalctl -xe» for details.

OpenVPN Server Service Won’t Start After Upgrade to Fedora 27

OpenVPN Server Service Won’t Start After Upgrade to Fedora 27

Post by rachelb4x4 » Tue Nov 28, 2017 4:38 am

After upgrading to Fedora Server 27, the openvpn@server.service wouldn’t start and said that it couldn’t find the unit. Prior to upgrading openvpn was working fine, and I was able to establish connections. I tried removing the symlink and adding a new one, but that didn’t work. So I tried uninstalling and reinstalling openvpn. Now the service is enabled, but it won’t start. Reviewing journalctl -xe shows the error message:
pam_systemd(sudo:session): Cannot create session: Already running in a session.

Has anyone see this or might know how to resolve this? I saw a few bug reports that may be related, but none with a solution.

I’m getting an error when trying to start an OpenVPN service on CentOS7

I keep having to reinstall the whole system and configure the VPN from scratch. Each time something new is causing problems. Previously the same error was countered with commenting ;explicit-exit-notify 1, but now it’s not enough and I’m out of ideas.

Job for openvpn@server.service failed because the control process exited with error code. See «systemctl status openvpn@server.service» and «journalctl -xe» for details.

The result of journalctl -xe is:

# to receive their IP address allocation
# and DNS server addresses.  You must first use

# Note: this mode only works on clients (such as

# Push routes to the client to allow it
# to reach other private subnets behind
# the server.  Remember that these

# to know to route the OpenVPN client
# address pool (10.8.0.0/255.255.255.0)

# To assign specific IP addresses to specific
# clients or if a connecting client has a private
# subnet behind it that should also have VPN access,
# use the subdirectory "ccd" for client-specific
# configuration files (see man page for more info).
# EXAMPLE: Suppose the client
# having the certificate common name "Thelonious"
# also has a small subnet behind his connecting
# machine, such as 192.168.40.128/255.255.255.248.
# First, uncomment out these lines:
;client-config-dir ccd
;route 192.168.40.128 255.255.255.248
# Then create a file ccd/Thelonious with this line:
#   iroute 192.168.40.128 255.255.255.248
# This will allow Thelonious' private subnet to
# access the VPN.  This example will only work
# if you are routing, not bridging, i.e. you are
# using "dev tun" and "server" directives.
# EXAMPLE: Suppose you want to give
# Thelonious a fixed VPN IP address of 10.9.0.1.
# First uncomment out these lines:
;client-config-dir ccd
;route 10.9.0.0 255.255.255.252
# Then add this line to ccd/Thelonious:
#   ifconfig-push 10.9.0.1 10.9.0.2
# Suppose that you want to enable different
# firewall access policies for different groups
# of clients.  There are two methods:
# (1) Run multiple OpenVPN daemons, one for each
#     group, and firewall the TUN/TAP interface
#     for each group/daemon appropriately.
# (2) (Advanced) Create a script to dynamically
#     modify the firewall in response to access
#     from different clients.  See man
#     page for more info on learn-address script.

# If enabled, this directive will configure
# all clients to redirect their default

# (The OpenVPN server machine may need to NAT
# or bridge the TUN/TAP interface to the internet
# in order for this to work properly).
