1.7.10 Not Connecting to MySQL Database

[XcelOrbit]

I have 2 1.12.2 servers which are perfectly capable of connecting to my database, however using the exact same config from the 2 that were working, my 1.7.10 server will not connect to it. It keeps attempting a reconnect and it errors with null. I'm running Thermos-1614 (EcoBridge Version 3.4.1), and it is tied into a Bungeecord network. So far, I tried letting it create a new config and putting my credentials back in, and I tried disabling SSL. Neither of those worked. Let me know if I'm doing something wrong, or if 1.7.10/Thermos isn't supported.
