Hi n8n lovers…:heart:
I have a problem using workflow.

In my case, When I start using docker, It is going well…

But… In, I got a message Error: connect ETIMEDOUT

What I tried

  • change Connect Timeout from 10000 to 50000
  • make new Credential
  • make new workflow(use same credential)
  • instance setting change n8n version 0.114.0 to 0.115.0

if someone can help, please reply thank you!

Hey @Alfie_Kim,

The process of how to whitelist an IP depends on the server you’re using. I would suggest you to go through their documentation to learn how you can whitelist an IP address.


hello harshil, thanks for helping out.

I’m running mysql node on n8n cloud and having the same error (connect ETIMEDOUT) even after I whitelisted IP. Is there something else I can try?

just fyi - I’m @Alfie_Kim 's friend and we working on the same project.
