Sonarrr

After installing Sonarr (NZBDrone) everythign worked fine at first. but after a reboot my raspberry pi won’t let me do

“sudo mount -a”

to mount my cifs shares.
I get the famous error 13 permission denied.

How can I resolve this. I already tried some of the solutiions for older mounting problems but they didn’t work.
