we have 'successfully' ugpraded to TC8 and the upgrade seems to have gone well - our web interface is back up and running with no problems at all.
Unfortunately, when attempting to start up any of the 4 agents we have, we get the message in the attached screenshot.
I've attached the teamcity-agent log file too.
The server is running on port 8888 so I can only assume we've misconfigured something as part of the upgrade process.
Any help would be gratefully appreciated. It's an enterprise license we have purchased, so I wasn't sure if I was supposed to post here or raise a support ticket, but thought I'd best do something!
If any more information/config/documentation is needed, please let me know.
