I set up a new hostname earlier this morning, mysql.mysite.com. About 10 minutes later I was able to reach phpMyAdmin at that URL. I went ahead and started setting up an application but then started to get connection errors. At this point, I noticed that when I went to mysql.mysite.com, I was actually being redirected to issac.sekhmet.dreamhost.com. If I use this as my hostname, I can see the DB I set up and don’t get connection errors.
