Add-ons web UI pane blank

In Home Assistant, HASSIO on a RP4, all add-on web UI panes don’t load and come up blank. I don’t see any error message. This is impacting things like not being able to see the Z-Wave JS to MQTT web UI.

How can this be troubleshot and resolved?

Try a force refresh of the bowser cache… what browser are you using ?

Brave/Chromium. Clearing the cache has no impact.

I did notice that Safari seems to be working on the same server. Maybe it’s something in the browser.

I reported the issue to Brave.

I am using Chrome. A force refresh worked for me. Thanks.
