Can't login, DB LOG: 'invalid length of startup packet' over and over again

[points-unknown]

Using the standard install script on my server, with some minor tweaks because I am not accessing from local machine (but from home server - so different IP). Everything seems to start fine, but then I can't login and I get this looping invalid length of startup packet error message from the database.

Logs below. Any help or insight appreciated.
