After updating to the latest v16 build, I am unable to connect to the CrashPlan Pro. I have verified all outbound connections are allowed to all of the crashplan's FQDNs. The Windows firewall is completely disabled on the server. I have completely disabled all outbound filtering on the server, and the issue persists. I can see the connection is established with CrashPlan in the firewall log. I have completely reinstalled CrashPlan on the server as well.
I only had issues after upgrading to v16.
