Add-on won't start in HASS

[JimmyMPage]

I am running Home Assistant OS on an ODROID N2+. I've installed the MASS integration and allowed it to install the add-on, but the add-on will not start. When I attempt to start the add-on, the spinning circle animates for a while, then the add-on does not start.

Here is the log from the add-on. I'm not sure what I'm looking at. I previously had MASS installed and running great, but ran into the recent issue listed here: #1343

I was attempting to remove and reinstall and now I'm running into this issue. I searched for this in the FAQ and discussion...I apologize if I missed something.

Did you update to beta41 ?

[JimmyMPage]

I just added a player group in the instance of MASS and the integration in Home Assistant updated with the player...so it's "seeing" the server. It appears the issue is just isolated to accessing the add-on within the Home Assistant UI.

[gieljnssns]

Have you tried to refresh the cache?

[JimmyMPage]

Thanks for that recommendation, I refreshed the browser cache and the add-on still shows stop and won't start. If there is another cache I can refresh, please advise. I appreciate the help. This isn't a HUGE deal now that I know the server is running and is able to interface with Home Assistant. I checked all of my automations that use Music Assistant and they are all functional. I don't know why I can't access the MASS UI from inside Home Assistant or why the add-on shows stopped even though the Music Assistant server is running at myinternalIP:8095, but the problem does not seem to be affecting the function of the automations and players associated with the integration.

[marcelveldt]

I have a feeling that it is running twice because it should run at port 8095 and not 8096.
Beta 42 will be available soon which also fixes some stuff related to this so please test with that and/ore restart the entire home assistant host

[JimmyMPage]

My apologies. I was going from memory. It's running at 8095. Original reply is edited. I will get the new beta installed and restart and report back once Beta 42 is available. Thanks for all the help!

[JimmyMPage]

This morning I updated to Beta 43. The UI is now accessible in Home Assistant and all seems to be working in that regard. Thanks!
