I'm sorry that my reply wasn't helpful but I don't fully understand what "performing the replication job using the same server as BR and Proxy" means. Are you saying that you attempted to use the same proxy for both source and target?
If you're on the forum looking for some "magic bullet" solution, I think it is unlikely. In my experience "unable to connect to port 2501" has always come down to some type of network connectivity, firewall or security software issue. If I were troubleshooting this issue I would look at the logs to determine what IP addresses are being used by the proxies, I would also monitor the proxies while a job was running and see if there is a VeeamAgent process listening on port 2501. Assuming there is (there certainly should be), then it pretty much has to be a network/security software issue. If there's not, then something with Veeam is not working correctly.
