The issue you are facing:
I migrated my nextcloud, from a VPS to an anopther one… Now, I finished the migration process, but when I access the nextcloud page, I get the internal error message page, instead of the maintenance mode on page.
Thanks you for your help !!!

I found the solution !
/var/www/nextcloud$ sudo -u www-data php occ integrity:check-core
told me that some files where missing
rsync didn t copy all the file.
Some files in 3rd party directory are with right 500, and could not be copy over to the new server.
I had to allow SSH loggin wioth root and rsync as root so it get copied witrht he correct rights.
