System.Net.Sockets.SocketException (98): Address already in use

[JBX 3]

I see this from time to time in the logging. What does it mean?

It means you already have another dlna app started and bound to port 1900.

That would probably be TVMosaic. I don't think I can turn it off or change the port number there.

Can I change the port number in Emby?

According to our investigations this is probably cause by changes to the .net core runtime.

 

Do you have a change to test this with the latest beta version which is using .net core 2.2?
