I’m running GameLiftLocal.jar with this parameters: java -jar GameLiftLocal.jar -p 9080
I have also tried to change port, same error.
And error is on attachment.
Trying looking up something like “what process is listening on a port windows” in google. Using one of those methods you can see what process is already holding open that port – usually it’s something you had forgotten or you ended up with duplicate processes somehow.
