Error establishing a database connection

In general, if something on your website is not working, please always share a URL to a page on your website where you can see that it’s not working. A database hostname alone, or a link to a page that doesn’t appear to use a database, doesn’t tell me anything.

And please always try to get the real error message from the database. WordPress has the WP_DEBUG flag you can enable to get the actual error message. “Error establishing a database connection” could be anything.

Actually, as I was writing this, the database connection appears to have come up.
