I am using a flexy 205 with Cellular. It has been working fine, but now it is offline in ecatcher. I have to plug directly into ewon now and it says VPN connection error. I tried cycling Power, and also the VPN wizard and still not working.
What is the error you are seeing in the VPN Wizard?
Can you send a backup with the Support Files? You can get this from Diagnostic > Files Transfer or using eBuddy.
