Good DAY!!
Tried to research the issue I am having before hand, but did not see anyone with the same problem.
Can recreate the issue on both my production OMV 2 and testing OMV 3 systems
I have the MySQL plugin running on OMV2 system which contains a couple of databases.
There is a backup job that runs and works great, so no issues with creating the .sql backup files.
However I have tried to restore the database on both my current OMV2 box and OMV3 test box, but get the same errors
1) I was getting an error the the file was to big to upload for Nginx
