Thing page in openhab UI not loading

Hello everyone,

sometimes I have the issue that the things page in OH3 UI is not loading.
All things are working fine and I can access all other pages like items, rules, etc. So only this page is not loading. Mostly when I check a day later it,s working.

It looks like this:

The blocks without text are flashing coninusly like a loading bar but even after minutes nothing is loaded. Inbox button and button to add new things are working fine too.

Any idea what could be the cause of this?

I have the same error in openHAB 4:

What can I do? In items page it is the same …

I already restarted openHAB, but error is the same.

Try Ctrl+F5 to clear the browser cache. Generally needed after an OH upgrade.
