For the EE Test server, you'll have to catch a DM or a Dev on the DM client there.
What I meant by reseting your password on the main server is this, once we migrate to EE, you'll be facing the same problem you are facing on the EE test server right now. Reseting your password by yourself on the main server will prevent that from happening once we migrate the main the server too EE.
Note : If you want to go on the EE Test server, poke me on Discord, if I'm there I can help you with reseting your password temporarily.
