This morning I update/upgrade packages in my Ubuntu 22.04.5 and discovered that snaps don't refresh. Snap returns this error message.
cannot refresh: cannot query the store for updates: got unexpected HTTP status code 503 via POST to https://api.snapcraft.io/v2/snaps/refresh". The Ubuntu Software app doesn't connect either. I have ping to api.snapcraft.io and snap was updated yesterday without errors. I didn't find any information for this case in the internet.
