Describe the issue
Going to server > Allow access for external clients > port and put an port more than 65535.

Configuration

  • UTM Version: Version 4.5.3 (99)
  • macOS Version: 14.5 (23F79)
  • Mac Chip (Intel, M1, ...): M1

I didn't foubnd where is the settings file to reset my mistake - UTM crash directly, so I can't change from GUI.
To resolv myself, I make UTM from source, remove server part (comment in UTMRemoteServer), and roll back settings to a good port.
You will just need check if port if not gratter than 65535.
