I almost upgraded our VCS servers to 8.6 last week and noticed a couple reviews on CCO so I stuck with 8.5.3. I’ll give 8.6.1 a try in a few days.

I had this issue this weekend in 8.6. My original issue was the "no home uds cluster" but I had issues with the proxy protocol violation. Tac's response was go to 8.6.1 (released 9/11/15 ... yikes) or roll back to 8.5 Thanks, Ryan -------- Original Message -------- From: Brian Meade <[email protected]<mailto:[email protected]>> Sent: Monday, September 14, 2015 03:49 PM To: [email protected]<mailto:[email protected]> Subject: [cisco-voip] MRA (Collaboration Edge) Intrusion Protection Is anyone else having issues with the "HTTP proxy protocol violation" automated detection feature or Expressway? I've got over 10,000 hits on this built-in rule and it seems to be blocking some legitimate logins via Jabber.

This particular user also has an 8841 at home. Is there a limit to number of MRA connections behind a single public IP? Thanks, Brian Meade
