Emby Server Log errors on fresh install

[EliteCube 6]

Why is on a fresh installed Emby-Server evertime error logs? Is this normal?

I see many Errors like this:

Initially you have credentials from the old server saved in your browser, and the new server is rejecting that. Nothing to worry about.
