[ERROR] Couldn’t connect to the Joomla database.

Yes, I have read and done these steps:

If Joomla and WordPress are not installed on the same host:
If you use CPanel on the Joomla server, a solution is to allow a remote MySQL connection.
– go into the Cpanel of the Joomla server
– go down to Database section and click “Remote MySQL”
– There you can add an access host (WordPress host). Enter the access host as the SOME-WEBSITE-DOMAIN-OR-IP-ADDRESS and click add host.

Another solution is to copy the Joomla database on the WordPress database:
– export the Joomla database to a SQL file (with phpMyAdmin for example)
– import this SQL file on the same database as WordPress
– run the migration by using WordPress database credentials (host, user, password, database) instead of the Joomla ones in the plugin settings.

It didn’t matter whether I imported the database locally (on my local server or on a web host), I still can’t make a connection. I’m sure many others have had great luck using the plugin, but I’ve spent nearly an hour trying to figure this out and can’t make it work.
