I am ususally running 4 instances of Sierra Chart. I noticed this error on Message Log. What may be the problem?
2025-01-21 15:31:24.520 | UDPListener (1668). Port 22904 | Error binding to UDP port: 22904. Windows error code 10048: Only one usage of each socket address (protocol/network address/port) is normally permitted.

Depending on what you are doing, that may not be an issue at all.

How are you running the 4 instances? How many are started using "File >> New Instance" and how many are actually separate installations?

In those sub instances set this to 0:
Sierra Chart Server Settings: UDP Port (Global Settings >> Sierra Chart Server Settings >> General >> General)
