Hi guys

Why am i getting these errors when unity starts up, even if i create a new project. It goes away and everything is normal but dont know why this happens.

there are 3 red dots with errors in the console

Socket: unable to join multicast group, error: An unknown, invalid, or unsupported option or level was specified in a getsockopt or setsockopt call.
(10042)

Unable to join player connection multicast group.

Unable to join player connection alternative multicast group.

any ideas?

Maybe useful: Socket: unable to join multicast group
Or try to reactivating license in Unity Hub. Maybe solve the problem.

Unity Hub → Settings → License Management → Check for Updates

or else you can re-enter your serial key by clicking on Activate a New License.
