MS Teams and WSA Transparent Proxy - Teams disconnects - Web Browsing reconnects

[cph24795]

We have all web traffic pushed through WSA via WCCP on a router.  At random times during MS Teams meetings, users will get disconnected.  A quick browser window session appears to re-authenticate the user and they can then rejoin the meeting.  We are using CDA/AD integration with the WSA's, so my understanding is that the reauthentication should be happening through that automatically.  Not sure why/how the web browsing is causing this.  Any thoughts or ideas appreciated...

when that happens, what is the WSA Logs shows? what model of WSA and version async code running on it.

is your Internet pipe ok, there are no disconnections? you need to bypass for teams if you can since most traffic goes to the MS Azure cloud.

Hi,

Did you find any solutions for this? I'm also having this issue.

We did not.  We ended up integrating WSA through ISE's passive identity and PXGrid services and removed CDA from the equation entirely.  The issue wasn't present after that change.
