Connection lost not connected

[Jon_Hallam]

Hi, ive searched this community and can’t see why this doesnt work. Im using Digitaloceans app platform and get n8n to load but says connection lost top right.

ive published here. https://dashboard-n-8-n-9xcik.ondigitalocean.app/

Im using this docker file - Docker Hub

with these environmental variables

N8N_VERSION = 0.91.0
N8N_PROTOCOL = http
WEBHOOK_TUNNEL_URL = publish link above
VUE_APP_URL_BASE_API = publish link above

what ever I try it never connects to the backend the front end shows the workflow designer page.

Welcome to the community @Jon_Hallam!

First. Never run n8n without basic auth activated as described here:
https://docs.n8n.io/reference/security.html#security
that is more than dangerous!

There is actually a lot written about this problem. Did you check out all the other posts in the forum? Here a few:

UI Connection Lost - Server-Sent Events

Hi, I’m getting this error yet I believe there is connection since the app works just fine when I interact with the UI, change or save something in a workflow. [image] This is happened after I configured a reverse proxy in front of n8n. Here is the setup: n8n.example.com points to nginx server. NGINX works as reverse proxy on nginx server. listen n8n.example.com 443 and redirects N8NServer:5678 n8n container works on N8NServer mapped to 5678:5678 n8n container deployed via docker-composed…

/!\ Connection lost with http reverse proxy Apache

Hello I’ve set an instance of n8n behind a reverse proxy Apache, with n8n basic authentication I can connect, browse, open WFs despite this orange message à top right, but I can’t execute them : ## Problem running workflow There was a problem running the workflow: No active connection to server. It is maybe down. Thank you

Connection lost

For me it works perfectly fine for me if I try with this most basic compose file: version: '3.1' services: n8n: image: n8nio/n8n:0.68.2-push-debug ports: - 5678:5678 command: /bin/sh -c "sleep 5; ./packages/cli/bin/n8n start"

Have sadly no idea how the DO App platform works. But if they also create a reverse proxy for you, it is possible that it will not work because n8n needs some special settings (as described in the issues above) to work. The reason for that is Event Source which we use to push information to the editor. So you can maybe check in DO forums if there are known issue with Event Source or check with their support.

If all that does network I would advise to get a regular DO instance and follow our Server Setup guide.
