Describe the problem/error/question

What is the error message (if any)?

I’m trying to use the human in the loop feature but it’s not receiving any response even after i click the approve button. it just keeps waiting. Do you know the reason for this?

Information on your n8n setup

i also see that the url when i click approve is:

http://localhost:5678/webhook-waiting/15260/a609d6e5-78f8-48b6-8db3-beabd8fbed27?approved=true

is that a reason? it should be my selfhosted domain right? not localhost?

yes. You need to set a proper public URL

Hi, I also have the same problem. I also run n8n via Railway with a webhook processor. Setting the proper public URL did not solve the problem for me.

I followed the instructions. this still doesn’t work.

did you check that the n8n is accessible from the Internet via that public URL and port?

Yes! I set up n8n on railway using the most used template.

Public url has always been accessible. Not sure what you mean by port ?

update. there was a recent update that fixed this issue. it seems it was just a bug.

I updated to : n8n Version 1.79.3 and it fixed the bug in the self hosted n8n for human in the loop
