Hi, actually when I revisit the binding, the username and password are still there. I cannot remove them. So, I delete them, click save, everything seems fine, but then I go back in, they are still input there. but if I change the server (like, cn,sg) that works, it remains saved.
So it seems my issues have nothing to do with adding/removing credentials because I cannot remove them. Now I suspect the issue may be happening due to the fact that the binding keeps retrying the cloud login endlessly…
I tried restarting the binding, disable/enable the thing, but now I keep getting these errors that usually show only once during startup of openhab. but now i keep getting them every 20-30min.
Maybe i will have to reboot the entire openhab but I hate doing that unless absolutely forced

I’m afraid to delete and recreate the thing, as I’m not sure will it work without cloud connection.
