"Listen for test event" does not work (but webhook call is received)

Questions
1

Hi,

I am getting into n8n since few days - first post, bare with me :slight_smile:
My first question is about the “listen fo rtest event” in the webhook node.
For some reason, it does not receive any data, listens forever.
But in the execution log, I see the calls coming in perfectly.

I am running n8n on a Hostinger VPS, did not change any setting in the docker-compose YAML so far. Everything is set on the defaults.

I have found similar issues here, in both cases it was a proxy_buffering setting in nginx.
But I am unsure if this applies to my setup and if, where to set this.

Can anyone help me on this?

Thanks, Simon

Oh, my bad.

I think I got the solution, writing it here for documentation:
Listen for test event is only possible for the Test URL.
Closing this :wink:
