MySQL 工作台错误：无法连接 SSH 隧道

Question

Full Error:

I am trying to establish a connection to a database instance in AWS EC2. I've spent hours looking at all the posts that exist on Stack Overflow and many other places related to this but nothing works for me.

I am able to use my.pem key to establish a connection successfully through PuTTY on my Windows 10 machine. I also am able to connect and use the database in dbForge Studio and DataGrip but I get this error when I use MySQL Workbench (I am trying to transition to the free software). I think this is something related to the key. Is there anything else required to do with the key after I downloaded it from AWS? Or does MySQL Workbench require anything different than dbForge or DataGrip?

Do I need to change the key format or add it to /.ssh folder or something along those lines? These are the tips I got from other answers but unfortunately, nothing worked for me. Any insights would be appreciated.

Answer 1

Can you please confirm the MYSQL hostname that you provided is local IP address 127.0.0.1 and the port number 3306. Because you're connecting over ssh and accessing the localhost inside the machine. And make sure to give proper read permission for your SSH pem file like chmod 400 my_test_key.pem . For your reference here I'm attaching a read.
