I am trying to update my server to 10.1.1 from 10.1 and I am not able to proceed due to the following error and this is on the primary server itself.

"The agent was unable to open the quick task port in the device firewall. The ZENworks server may be unable to contact the agent."

Message ID: ZMD.FailedToOpenQuickTaskFirewallPort

This is running on SLES 10 SP2

Nothing changed to my knowledge prior to this happening. I have searched and found no solution to this issue. I am getting other errors trying to upgrade, but I am almost certain it is all due to this issue.
