I have just gone through the process of Migrating my GW system, from NW to OES2, and then upgraded from version 7.x -> 8.x however now I am having some weird issues. The POA will load, but immediately unload when I load the GUI screen it gives the following error message

"TCP/IP port already in use (8555). Port Specified:1677 [OK] not sure what happened.

When I check in C1 things look correct, and I have gone into the GWHA.Conf and though there were a few additional items, which I have remarked out, nothing seems to really jump out at me.

What would cause the 8555 error?
