Ableton port not available 

So, 

I got this working with Ableton 11 by updating it to Python3 (Ableton updated their scripting to Python3)

BUT, now I got a new issue when I pick the LiveOSC2 script in Ableton I get an error that port 9001 already is in use. 
So I was like ok then let's change the port, but now I get the same error in Ableton with the new port.

anyone that got a solution to this?
