For the user who update the desktop app from version 1.0.5 or lower to 1.2.0, there is a change the way the app connect to OBS websocket. The user need to reconfig both port (and password) on Settings, even though the port is already filled by '4444'.
For fresh install, there will be no problem connecting to OBS. However, on the updated app, the port should be null, not '4444'. This is a bug in renderer side (my bad). It's also the same for Streamlabs OBS config.
So, the temporary fix for this: delete the text in port text filled, then refill it with '4444' or setting.

Sorry for the inconvenience.
