I think I have at least part of my issues corrected lol. Somehow, before the update when I shut down the server, it didn't kill the chatserver for some reason. I didn't even notice it was still running until now. That probably explains the port issue I was having at first and also the key mismatch if chatserver was still trying to use the keys as well.
I think I will probably have to do another server reboot for all of the changes I made to take effect fully. Hopefully that will get rid of these problems completely. It's really cool that you were able to get this coded, BTW
EDIT: Rebooted the server and it seems like that corrected the issues. So far, the new UCS seems to work perfectly. I will keep an eye out for any issues, but I don't expect anything major.
