Cisco AnyConnect Constantly Reconnecting on Macbook Pro

[brandonleetran]

Hi Folks,

In the past month my VPN AnyConnect is constantly reconnecting. From every 3 minutes to every 15 minutes at times. This is a major blocker for attending meetings and workflow interruptions. 

I've tried various changes from IPv6 disabling to MTU adjustments but none of these tweaks are correcting the problem.

Macbook Pro 15-inch, 2018

macOS Mojave 10.14.5

Cisco AnyConnect Secure Mobility Client Version 4.7.01076

AT&T Gigabit 

Router Model	5268AC
Hardware Version	260-2173300
Software Version	11.1.0.531418-att

I did do a test and spent 1.5 hours at Starbucks connected to the VPN with no issues. What is it with AT&T and Cisco combination that is causing the constant reconnects?

Thanks for any help.
