I really like using the HTML5 vpn for quick and easy administrative tasks in our organisation but I have been having issues with the remote connection getting closed unexpectedly. The error on the screen shows that the 'connection has been closed due to configuration changes' but no changes have been made.
The timing of this is completely random, between 5 minutes and 30 minutes and seems worse when you are not doing any real work on the session (i.e moving the cursor around etc.)
When I look at the logs this is what I found:

I have taken a look at nearly every other post that has reported a similar issue and made any changes I could find but the problem remains.
The issue happens even if I access the portal on the internal network. I'm sure you will need more information from me if anyone can help and I would be happy to supply whatever config info to assist.
Any help greatly appreciated.
