Not sure of root cause - but a hint from another thread suggested I drill down to ESPHome in the add-on store and try the update from there. Lo and behold it worked… Go figure.
Hi zoogara, we tried this the other day as we had the same problem but we could only see the official add-ons and not any of the Home Assistant Community Add-ons. Glad this worked for you
If your reading this and can’t see the Home Assistant Community Add-ons I posted how I resolved this problem on the link below.
