When accessing my node GUI via Google chrome I see an empty app store and a warning that the SD card is close to failure. When logging on in Firefox everything looks normal. Not looking for help with this, just want to mention it in forum in case others encounter the same errors: Changing browsers may help. Clearing the cache, cookies and history in chrome brought things back to normal. No idea why this is, though.
Interesting, I’ve never seen this issue before.
If that issue comes up again and if you don’t mind, on chrome, open developer tools ( Option + ⌘ + J (on macOS), or Shift + CTRL + J (on Windows/Linux)), select network and refresh the page. If you see any of the API requests have failed, you could probably click on them and see why they’re failing.
