Use SU. Go to the Folder hosting NextCloud with the occ file. (This step should look evidence for everyone , but I am Noob hahaha, I give advices for Noob   ) And write this : Here , you can do this : sudo -u www-data php occ files_external:list You can see the bad External Drives and delete it with : sudo -u www-data php occ files_external:delete X Then , you can re-create good ones by using this command : sudo -u www-data php occ files_external:create Blabla ‘sfpt’ password::password -c host=X.X.X.X -c share=/X/ -c root=/X/ -c domain=workgroup -c user=X -c password=X Replace : X with Yours  Have a nice day
