Connecting to MySQL hosted on Render.com via docker - (SQLSTATE: HY000)

[obj63mc]

What happened?

I am currently hosting a MySQL database, 8.4 and 9.7 on various docker containers using the official mysql docker images at render.com. When trying to connect via TablePro I am always getting the following error

[2013] Lost connection to server at 'handshake: reading initial communication packet', system error: 60 (SQLSTATE: HY000)

I am connecting using an ssh tunnel directly into the docker container and then have tried 127.0.0.1, localhost and the docker service name for connection. All return the same error. Using DBeaver though, that app can connect fine.

I have also tried using the MariaDB option for connection but it just returns the same error as well.

This is similar to #338 and #747

Steps to reproduce

1. Setup Docker Container on Render.com for MySQL
2. Setup connection with SSH tunnel
3. Connect, ssh works, mysql connection then errors out.

Expected behavior

This should be able to connect, other applications can connect with the same configurations.

Database type

MySQL / MariaDB
