Everything appears to have installed correctly, but after the service should be running, I visit the appropriate url (I have a custom port set in the correct yml file) and rather than any interface, I get the following error:
Fatal Error - sorry this shouldn't happen. SQLSTATE[HY000]  Access denied for user 'cms'@'172.18.0.5' (using password: NO)
Looks like a sql connection problem, but I didn’t touch any settings relating to the database. Any thoughts on how to resolve this?
