You don't have an UniAccount (but a permission to use the VPN service), there is a special website to change the password:
[WLAN, VPN] Problems with the connection with a Vodafone station
If you have a Vodafone Station router, occasional reboots of the device will help to fix problems with WLAN or VPN.
[VPN - Windows] When the VPN connection is active, only the browser has an active Internet connection.
If you are connected to the VPN and can use your browser, but no other application can connect to the Internet, this may be related to the Windows firewall.
In this case, it may help to reset your firewall settings to default.You can follow these instructions to do that.
[VPN - Windows 11] Pulse Secure does not work under Windows 11.
Please use Pulse Secure version 18.104.22.168 or newer(found here).
The usage of the Pulse Secure Client from the Windows Store is not recommended, because it does not provide all funcionalities of our Client.
Uninstalling the Pulse Secure Client from the Windows Store:
Press the Windows-Button => Click the gear icon (Settings) => Click on Apps => Scroll down to "Pulse Secure (Pulse Secure LLC)" and uninstall it
Afterwards our Pulse Secure Client can be installed.
[VPN - Forcepoint] Loss of connection with Connectbox from Unitymedia/Vodafon
If you connect to the VPN via a Unitymedia/Vodafon connectbox and the connection is terminated after a short time, this can possibly be prevented by setting the MTU to 1280.
In the Forcepoint window, go to the Advanced tab.
You can then change the MTU by clicking on the field and entering 1280.
Press Apply at the bottom to confirm the change.
You must restart the computer for the change to take effect.
See routing table in terminal:
If there is an entry for
Pulse Secure: 22.214.171.124 (vpn.tu-dortmund.de)
or Forcepoint: 126.96.36.199 (stud.vpn.tu-dortmund.de)
then delete it:
Pulse Secure: sudo route -n delete 188.8.131.52
or Forcepoint: sudo route -n delete 184.108.40.206
open etc/hosts file. If there is an entry for
Pulse Secure: 127.0.0.1 vpn.tu-dortmund.de
bzw. Forcepoint: 127.0.0.1 stud.vpn.tu-dortmund.de
then please delete it.
[VPN - Strongswan(Linux)] Loss of connection with Connectbox from Unitymedia/Vodafon
If you connect to the VPN via a connectbox from Unitymedia/Vodafon and the connection is terminated after a short time, this can possibly be prevented by setting the MTU to 1280.
Open the command prompt.
Run the ifconfig command and search for the WLAN/LAN adapter you are connected to the Internet with. On the left you will see the name of the adapter and after the term mtu the value for the MTU.
You can set the MTU value to 1280 using the following command:
ifconfig (name of the adapter) mtu 1280 up
You can then connect to the VPN.
The MTU setting is not persistent and will be reset on the next reboot.
Since we do not recommend changing the MTU persistently, you must thus change the MTU before each VPN connection (provided the computer has been restarted since the last connection).
no EAP key found for hosts 'ipsec.stud.vpn.tu-dortmund.de' - '[Uniaccount]'
please check if the /etc/ipsec.secrets file is correct. It should look as following:
[Uniaccount] : EAP [Password]
Also confirm that there is an empty space after the Uniaccount.
