Hi,
When I tried to open my Nextcloud in a web browser suddenly did not work and when i tried to log in to MySQL it is throwing errors and when I am checking occ status it is also throwing an error I cant find where the issues are?
Steps to replicate it:
- I cannot open MySQL login.
- I cannot able to check the occ status
- i cannot able to login Nextcloud browser login page
