Issues after migrating to OH3 - Unauthorized API request: Invalid Basic authentication credentials

Hi all,
I have an OH2 installation and I am installing OH3 from scratch using openHABian.

After the installation, I noticed the following recurring error message every 5 seconds in the log:
2021-02-15 23:03:25.997 [WARN ] [ore.io.rest.auth.internal.AuthFilter] - Unauthorized API request: Invalid Basic authentication credentials

I tried to enable or disable the “Basic Authentication” in the API security section, but this warning still remains.

Any idea?

thanks

My installation (openhabian, too) is showing the same frequent log entries. Did you found a solution?

Do you access the REST API ? Did you try to use an authentication token then ?
