Encountering "connect ETIMEDOUT" error when connecting to MySQL database in n8n workflow

Ashny7 · July 23, 2025, 9:42am

I’m facing an issue with the MySQL node in my n8n workflow, where it throws an “Error: connect ETIMEDOUT” when attempting to connect to the database. The error occurs during the createConnection step, as shown in the stack trace below. I’ve checked the database credentials, host, and port, and they seem correct, but the issue persists. Could this be related to network connectivity, firewall settings, or MySQL server configuration? Any suggestions on how to troubleshoot or resolve this would be appreciated!

Where did you run the mysql db and n8n? Do you use docker for that?

Ashny7 · July 23, 2025, 10:07am

The MySQL database is running on a host named devux-db.vih.infineon.com, which is not a Docker container.
The n8n instance is hosted on a server with the hostname n8n-mntechecklist.eu-de-3.icp.infineon.com, which is also not a Docker container.

Have you been trying to connect the mysql db in your local computer?

Ashny7 · July 23, 2025, 10:22am

yes I’m connecting mysql db from local computer

It’s kinda weird, can you show us the workflow by embed the workflow here?

cutecatcode · July 23, 2025, 11:11am

You need to upgrade your workflow:)
To upgrade, replace the node one-by-one

Ashny7 · July 23, 2025, 11:17am

What exactly do i need to upgrade?

cutecatcode · July 23, 2025, 11:25am

n8n version and nodes

Ashny7 · July 23, 2025, 11:44am

Thanks for the suggestion… But currently it is not feasible to upgrade the n8n version as another application is being dependent on this workflow. Is there any other way that this issue can be solved?

cutecatcode · July 23, 2025, 11:45am

can you just show us the n8n version here?

Ashny7 · July 24, 2025, 5:56am

@cutecatcode Could you please let me know which version would be better to use as I have faced issue where the workflow was affecting the dependent application last time

@cutecatcode
is it possible to view the executions that have been failed from last one week?
I’m able to see only executions from last 2 days

cutecatcode · July 24, 2025, 6:32am

If you’re using self-hosted, it can view the executions more than one week (maybe), but I don’t know if you’re using self-hosted or not.

cutecatcode · July 24, 2025, 6:33am

You’re using very old n8n version, please upgrade to newest

Ashny7 · July 24, 2025, 7:10am

Thank you @cutecatcode so much for your help

Ashny7 · July 24, 2025, 9:53am

These are the environment variables … could you please look into this and help with any details that would resolve this issue… And could you please suggest how can we store the failed execution so that we dont loose the data
