meteohub.de

and I don't know how to get it back. The URL is setup in weathercam but when I go to the weather network it won't come up.

Check to see if your webcam changed IP.
See if the URL still produces and image if you copy and paste it into the browser address bar.
Some cameras have a security lockout where if the password is entered in wrong too many times it locks out....reboot the camera to skip waiting for the lockout.

I copy and paste the URL from the weather cam and it works, but those images on the weather network tab won't.
