Sometimes the simple stuff seems the hardest.
In my case I am working through the Symfony 4 update to the Symfony Deployment course and somewhat unusually, am not doing anything in dev, but lots of stuff in prod.
The reason for this is that I have forked the official Symfony demo project, and have slightly modified it for my needs. As it’s an official demo project, it’s pretty much guaranteed to work.
I had a production server set up, and had deployed my code.
I’d set up my environment variables – I believed, correctly. But when I hit the site:
“Authentication request could not be processed due to a system problem.”
I do enjoy a good error message.
The fix was simple in my case. I had set the wrong path to the database:
DATABASE_URL=mysql://dbuser:dbpassword@127.0.0.1:3306/db_dev
And what it should have been:
DATABASE_URL=mysql://dbuser:dbpassword@127.0.0.1:3306/dev_db
The db name was back to front.
In prod, the log files give no help around this, at all.
I had to spin up the dev environment where things are a lot more evident:

The give away line being:
Access denied for user 'dbuser'@'%' to database 'dev_db'
Typos, such fun.
Anyway, easier to fix than it might otherwise appear. Hopefully it is for you, too.
