Currently having issues connecting to my server with playit. ("Internal Exception: Connection reset")

Hello, my server recently developed an issue that prevents all (non-local) users from connecting. Seems to be an issue with playit, does anyone know what might be causing this?

(Willing to provide any useful info to help problem-solve)
(The error message: “Internal Exception: Connection reset”)


I have same problem, too.
Non-local user always have this error after several minutes.
