Hello @szaimen,
thanks for your reply.
I found a solution in another thread: Can't remove external mount - #11 by SimpleCake
Solution by User SimpleCake:
Open a docker interactive terminal (if you’re using docker with the official image)
sudo docker exec -it docker-nextcloud /bin/bash
List the currently active mount points for all users
Standard Usage
occ files_external:list -a
Docker
su -c "php /var/www/html/occ files_external:list -a" -s /bin/sh www-data
Delete a selected mount using the mount’s ID
Standard Usage
occ files_external:delete <Mount ID>
Docker
su -c "php /var/www/html/occ files_external:delete <Mount ID>" -s /bin/sh www-data
Command results for reference
These commands were issued from inside a docker container, so they command syntax will look different if you’re using the terminal (as discussed previously) or if you are using a different image base in your docker container.
List ALL of the mount points as the root user
root@mydockercontainer# su -c "php /var/www/html/occ files_external:list -a" -s /bin/sh www-data
+----------+-------------+-------------------------------------+-----------------------+----------------------------------------------------------------------------------------------------------+---------+------------------+-------------------+----------+
| Mount ID | Mount Point | Storage | Authentication Type | Configuration | Options | Applicable Users | Applicable Groups | Type |
+----------+-------------+-------------------------------------+-----------------------+----------------------------------------------------------------------------------------------------------+---------+------------------+-------------------+----------+
| 2 | /BoxDotCom | WebDAV | Username and password | host: "dav.box.com\/dav", root: "NextCloud", secure: true, user: "emai1@local.com", password: "***" | | user1 | | Personal |
| 3 | /GDrive | Unknown storage backend googledrive | OAuth2 | configured: "true", client_id: "xxxxxx...al.com", client_secret: "***", token: "***" | | user2 | | Personal |
+----------+-------------+-------------------------------------+-----------------------+----------------------------------------------------------------------------------------------------------+---------+------------------+-------------------+----------+
Pick out your ID from the results
I choose number three which is associated with the provider type and user that is having the issue.
Delete the mount and confirm when prompted
root@mydockercontainer# su -c "php /var/www/html/occ files_external:delete 3" -s /bin/sh www-data
+----------+-------------+-------------------------------------+---------------------+--------------------------------------------------------------------------------------+---------+------------------+-------------------+
| Mount ID | Mount Point | Storage | Authentication Type | Configuration | Options | Applicable Users | Applicable Groups |

| 3 | /GDrive | Unknown storage backend googledrive | OAuth2 | configured: "true", client_id: "xxxxxx...al.com", client_secret: "***", token: "***" | | user2 | |

Delete this mount? [y/N] y
List ALL of the mount points again to ensure it’s gone
root@mydockercontainer# su -c "php /var/www/html/occ files_external:list -a" -s /bin/sh www-data
