Missing icons and error message

Just today I noticed a few icons went missing, such as the “contacts” icon (between the bell and avatar). I’m also missing things in the Contacts application.

I’m using an up to date NC19, client side I’m using Firefox 78.3.0esr with no plugins.

I’m seeing this in the logs:

OCP\Files\NotPermittedException: Could not create path

(not sure where to post this or what tags to add).

I went over everything and found something odd in “Trusted servers”. There was a server listed that was marked in red (nx12011.your-storageshare.de). I deleted that and everything went back to normal, instantly.

I’m not sure how any of this is linked, but it appears it is. All errors are gone and the sun is shining again.
