We're a much smaller deployment but have started seeing this some as well. Early on we were getting more consistent errors with the PPP tunnel related to RAS 720 errors ( https://support.f5.com/csp/article/K10445740 ) and conflicts with our Zscaler tunnel.

 

There are some very old topics on this, but yours is the newest and most verbose so I'm happy to bump and upvote to promote more up-to-date discussion.

 

Mine is not consistent as I survey the user base, and I am hoping those I am seeing are just the result of the local connection transitioning on the laptop. Only one complaint so far, so it's unclear if this is actually a problem for us. What is your interval like for flapping? Is it consistent throughout the day?

 

The local log file ( %TEMP%\logterminal.txt ) was helpful for solving our previous more consistent issues. We have left instructions with our support desk to retrieve this in the event of further complaints.
