Is the IDE Cloud9 addon blocking my access?

Hey folks,

I seem to have lost access to my Hassio interface all of a sudden. When I go to the address of my Pi, I end up in the Cloud9-addon instead. Is there any way of getting around this?

In the log I get:

2018-03-17 07:31:59 ERROR (MainThread) [homeassistant.components.http] Failed to create HTTP server at port 8123: [Errno 98] error while attempting to bind on address (‘0.0.0.0’, 8123): address in use

For anyone in the same situation: My suspicion was right, the IDE add-on was blocking the web interface, because I had set the same port 8123 for the add-on. That blocked access to the interface. The solution was to stop the add-on through ssh and then changing its port after I restarted and got to access the web interface.
