Function Cold Start Error

I am getting this error:
Multiple internal curl errors has occurred within the executor! Error Number: 111. Error Msg: Connection refused\nError Code: 500

It appears to only occur when the function is cold. Rerunning the same request, solves the problem.

What's the runtime?

And what's the function code?

Node

I can’t share it right now bc I’m not at my computer. But it functions as a webhook that is used to mint cryptocurrency tokens when it receives events.
