VPS - Docker - Serverpilot | Connection lost

Questions

Hi,

I really hope someone can help me as I already tried all kind of configs I found in the forum.

My setup:
VPS
Docker
N8N
NGINX (configured by ServerPilot)

My config looks like:
docker_compose.yml:

version: "3.8"

services:
  n8n:
    image: n8nio/n8n:1.94.0
    restart: always
    ports:
      - "5678:5678"
    environment:
      - N8N_HOST=automation.mydomain.at
      - N8N_PORT=5678
      - N8N_PROTOCOL=https
      - N8N_EDITOR_BASE_URL=https://automation.mydomain.at
      - WEBHOOK_TUNNEL_URL=https://automation.mydomain.at
      - N8N_PUSH_BACKEND=websocket    
      - N8N_BASIC_AUTH_ACTIVE=false
      - N8N_ENFORCE_SETTINGS_FILE_PERMISSIONS=true
      - N8N_RUNNERS_ENABLED=true
      - VUE_APP_URL_BASE_API="https://automation.mydomain.at"
    volumes:
      - ./n8n-data:/home/node/.n8n

my nginx-app.conf.erb (overrides the vhosts):

server {
    server_name automation.mydomain.at;

    location / {
        proxy_pass http://127.0.0.1:5678;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        proxy_buffering off;
        chunked_transfer_encoding off;
        proxy_cache off;
    }
}

When i open n8n I see this error and can not run my automations:

2025-06-16 15_34_50-AnyDesk
2025-06-16 15_34_50-AnyDesk500×709 24.4 KB

I already tried several different configs found on the forum but nothing helped so far. Also tried to downgrade → Same. It probably has something to do with nginx but I’m not sure how to dig deeper.

Really appreaciate your feedback.

Thanks and BR from Austria,
Niko

2

are the logs clear. don’t you see the error info in the logs?

3

which error logs are the most interesting? I will provide them of course. Sorry, I’m not super familiar with servers.

4

p.s.: nginx error log ist leer.
docker compose log auch ohne nennenswerte fehler (läuft ja theoretisch auch - also ist ja über den browser aufrufbar)

5

docker logs -f container id. should show any issues

That looks pretty much OK, or not?

ya , looks ok. how about access logs and error logs

/srv/users/serverpilot/log/automation.mydomain.at/access.log

tail -f /srv/users/serverpilot/log/automation.mydomain.at/error.log

Thanks a lot for your help so far. here are the anonimized log files.

The most intersting one is probably: the n8n_apache.error.log. Here are some lines (full code above):

Looks like a proxy error but I dont know how to solve it? hmmm…

Check if n8n is actually listening on 127.0.0.1:5678 or 0.0.0.0:5678:

docker inspect <container_id> | grep -i “IPAddress”
or
ss -tulnp | grep 5678

If it’s not on 127.0.0.1, update your NGINX config to reflect the actual internal IP.

Here is the full output because with “grep ip” i didnt get a result:

Does it mean, its not listening to 127.0.0.1 or localhost? But why can I access it, if its not listening?

Not sure why my reply with the output was flagged and removed because it was anonymized but however.

I removed the rest of the output:

v220241254037301857:~# 6
tcp liste      127.0.0.1:5678       0.0.0.0:*

I’m not sure why but my replies get flagged autmatically. But the output says its listening to localhost on port 5678
