Webhook tunnel not working - no in real time items being passed between nodes

[JB27]

Hi! Pulling my hair out trying to solve this - not a clue what’s going on.

Describe the problem/error/question

N8N is live on custom domain via docker and nginx but webhooks and live data passing between modules (ie. the green x items as you run the workflows) are not working. I believe this is an issue with the webhook tunnel.

I have set my webhook tunnel url correctly with https://n8n.mydomain.com. SSL managed by letsencrypt

What is the error message (if any)?

Apologies if this is too much or too litte info - proper novice at this but keen to learn!! Thank you so much :)

Hey @JB27,

I would start by going through the docs and removing the env options that are no longer needed.

To actually fix the issue though you will need to update your nginx configuration to support websockets. I would recommend using Caddy or Traefik instead as they automatically support websockets.

Thanks so much Jon - really appreciate the help.

The env variables added at the end were an attempt to rectify the issue based off suggestions in the forum around bugs in latest version.

I have completely deleted Nginx and tried Traefik instead per the docker compose guide and it’s working perfectly!! Thank you so much - love the product and it’s brilliant to have it working again!
