Also make sure that the mysqld.exe is not I/O thrashing as that can cause you to be stuck at connected. Get process hacker, then monitor the mysqld and see if the I/Os are high or not. If that is not the issue, then perhaps you did not set the /mop_auth/realmlist address to your local IP. You will need an SQL editor to access the database. If you have no idea what you are doing, back it up first BEFORE you attempt to modify anything just in case you modified something wrong. I learned how to use the SQL database the hard way with an old 2013 TrinityCore Wrath of the Lich King repack and I nuked it many times learning.
