Symptom: After upgrading to PAM 2.8.1; customer is not able to launch any RDP/SSH connections target servers.
Error: Existing connection was forcefully closed by the remote host due to time out while connecting to any backend servers through PAM
Engineering Notes: Being the cluster is up and ALL GREEN for Access and PA, then the UPD process may have stopped and needs to be restarted. Assuming that that node that is unresponsive with RDP error not being able to reach the backend device, all we needed to do is login through SSH and restart the process at the command prompt: xcd_upd. The usual workaround for this problem of disabling the Retrieve IP address feature from Global Setting and restarting UPD didn’t work.
