Cisco Anyconnect VPN 4.4 breaks invoker

[ralphy006]

After upgrading our Anyconnect client (from 4.2 to 4.4), Invoker seems to be broken while connected to the VPN.

Anyone find a workaround?

EDIT: This issue is specifically for MacOS, Sierra

Which OS?

Sorry, should've mentioned that.

MAC, Sierra

This is going to be tricky to fix without some help from you. when you say breaks - I assume you mean "foo.dev" feature stops working?

[ralphy006]

something like test.dev displays a pager ("Yay you are on rails!")

When on the VPN (4.4+), it says page cannot be found.

It looks like the VPN client causes the traffic to get reset

I'm seeing the same on macOS 10.15.7 with Pulse VPN installed (even if the Pulse app isn't running). Any luck finding a workaround @ralphy006?

Update: apparently it was McAfee antivirus, specifically a process called fmpd
