Hi all, I was looking for Xiaomi gateway addon and couldn’t find it.
In add-on store I did have the community add-ons initially.
Firstly I tried adding the Xiaomi Gateway ( …home-assistant.io/integrations/xiaomi_aqara/ or …github.com/home-assistant/core/tree/dev/homeassistant/components/xiaomi_aqara ) repositories via the “Manage add-on repositories” and got the “Not a valid add-on repository”.
I did noticed the https://addons.community repository was present in the “Manage add-on repositories” window.
I tried different repositories links, including …addons.community/edge/ which should work, but same error.
Then, as a test, I deleted the https://addons.community repository from the “Manage add-on repositories” window and tried to re-add but I get the same error “Not a valid add-on repository”
Please note that before I removed the community repository, add-ons from it were installing OK, for example the Visual Studio code and SSH&Web Terminal (not the official Terminal&SSH) are working OK.

The install I have is in virtual box on intel hardware and the log shows as below:

I did search both forum and web about this but everybody seems to just enable the advanced mode and all good, but I did enable the Advanced Mode already and rebooted it a couple of times.
