This Post is a collection of WatchGuard SSL VPN Issues known to me and how to solve them.

 

Error:

• SSL VPN session is closed directly after connecting
• The session is visible in the System Manager for only 1-2 seconds
• There is no error in the client log

Issue:

• You are using an SSL VPN Client Version that is older then the WatchGuard Firmware

Solution:

• Install a newer SSL VPN Client Version
