I’m having trouble with MySQL Workbench Community when trying to connect via SSH. Despite entering the correct credentials and settings, the connection fails. Does anyone know what steps I should take to resolve this issue?

I’ve been pulling my hair out trying to connect to my MySQL database using MySQL Workbench Community, and I desperately need some help. I’m attempting to connect via SSH, which I thought would be pretty straightforward, but it’s turning into a major headache. I’ve double-checked my credentials and settings, and everything seems to be correct – at least, I think so!

Here’s what I’ve got so far: I’m using the right username and password for the SSH and the MySQL server. The host is correct, and I’ve even specified the port number, but every time I hit “Test Connection,” I get a failure message. It’s so frustrating because I feel like I’ve done everything by the book.

I’ve looked into a few potential issues online – like maybe my local firewall could be blocking the connection or that the SSH service on the server isn’t running. I tried disabling the firewall for a little while, and that didn’t help. I also verified that the server is indeed reachable; I can even SSH into it using a terminal, so the connection works there. But somehow, MySQL Workbench just won’t cooperate.

One thing I noticed is that sometimes it throws a “Could not connect” error without much detail, and other times it mentions something about a public key issue. I know a little about SSH keys, but I’m still not sure how to troubleshoot that part. Do I need to specify a key file somewhere? If so, how do I do that in Workbench?

I’m starting to feel a bit overwhelmed here. Has anyone else run into this kind of problem before? If you have any tips, tricks, or step-by-step guides, I’d really appreciate it. I just need to get this connection up and running so I can get back to work. Any insights would be super helpful – thanks in advance!

    1. MySQL Workbench Connection Help

      MySQL Workbench Connection Woes

      It sounds like you’re really in a tough spot trying to get MySQL Workbench to play nice with your database! Here are some things you could check or try:

      • Double Check SSH Settings: Make sure you’ve got the right IP address for the server, and for the SSH port (usually 22). If you’re using a different port for SSH, you need to specify that.
      • Use the Right SSH Key: If you’re using an SSH key for authentication, make sure it’s added in MySQL Workbench.
        Go to the ‘SSH’ tab in the connection settings, and there should be an option to specify your private key file.
      • Testing with `ssh` command: Since you mentioned you can SSH directly from the terminal, try connecting like this: 

        ssh -i /path/to/your/private_key user@yourserver.com

        This helps confirm your key is working.

      • Firewall Settings: It’s good that you disabled your local firewall. Just make sure there aren’t any firewall rules on the server itself that could be blocking access.
      • MySQL Server Running?: Check if the MySQL server is actually running on the remote machine. If it’s not started, that would lead to connection issues.

      For the public key issue, that typically pops up if the server isn’t recognizing your key. In the SSH setup of MySQL Workbench, ensure that the SSH Key file matches what you’ve got on the server:

      • Go to the connection settings in Workbench.
      • Under the SSH tab, find the field for the SSH Key File and point it to your private key.

      If you’ve done all that and it still doesn’t work, maybe check the logs on your MySQL server for more clues. It can give hints if the connection is failing on the server side.

      Don’t lose hope! It can be tricky, but once you figure it out, it’ll be smooth sailing from there!


    2. It sounds like you’re experiencing a frustrating issue with connecting to your MySQL database via SSH using MySQL Workbench. First, ensure that you have the correct SSH settings configured. In MySQL Workbench, when setting up your connection, you need to go to the “SSH” tab and input the SSH Hostname (this is typically your server’s IP address), the SSH Username, and the SSH Password. If you’re using an SSH key for authentication, make sure to specify the path to your private key file in the “SSH Key” field. Check that your public key is properly added to the authorized_keys file on the server, as this is essential for authenticating via SSH. If you’re still facing issues, I recommend reviewing the logs for any error messages that might offer further insight into what’s going wrong during the connection attempt.

      Additionally, since you’re able to SSH into the server using a terminal, this suggests that the SSH part is functioning correctly. The issue may reside specifically within MySQL Workbench’s configuration. If you continue to receive a “Could not connect” error or a public key issue, double-check the following: ensure that the MySQL server is set to accept connections from your SSH user, and verify that you’re using the correct MySQL port (default is 3306). A common stumbling block might be the MySQL server’s bind-address in its configuration file (my.cnf), which should allow connections from the SSH host. Lastly, as a last resort, ensure that you have the latest version of MySQL Workbench, as updates may fix underlying bugs. If the problem persists, consider examining MySQL Workbench’s documentation on SSH connections for further guidance.
