Solved Couldn't create server on port 28015 (unknown)

I Removed "+Server.IP x.x.x.x" and it seems to have fixed it.

 

That just means that you're running a local server, and not one that is available to players besides you.

 

Having the same issue. Trying to get RustIO to work, but it isnt responding. Setting any Server.IP parameter wont allow it to start. Not having it wont let RustIO get the map.

 

having the same issue, ugh. this is annoying.

i think it's an issue with portforwarding, i can't seem to get my ports to open.

 

had this just happen to me found out it was multiple processes running in background not sure how that happened but it's now fixed thanks for the post..
