Docker with traefik -- no log error -- page 404

Questions
#1

Hello. So I took a good look at the other relating threads on this but the suggestions & solutions haven’t worked-out with this specific setup. I should warn, I have little understanding of what i’m doing.

I have docker on ubuntu server 2.04 with traefik & portainer running fine. I played with n8n desktop & thought I set it up over to this same server in hopes of not having to deal with nginx.

/home/user/ is where all the files are saved. Thinking of using /home/user/n8n/data/.n8n to hold the config, database etc.

/n8n has the following docker-compose.yml
I did make variations with different labels, environments, & volumes but this one is the last tried copy.

The .env file:

I did try a few versions with different directories for the data_folder but userSettings defaults to /home/node/.n8n/config

Summary

Folder where data should be saved

DATA_FOLDER=/home/user/n8n/data/

The top level domain to serve from

DOMAIN_NAME=domain.io

The subfolder to serve from

SUBFOLDER=n8n

N8N_PATH=/n8n/

The subdomain to serve from

SUBDOMAIN=n8n

DOMAIN_NAME and SUBDOMAIN combined decide where n8n will be reachable from

above example would result in: https://example.com/n8n/

The user name to use for autentication - IMPORTANT ALWAYS CHANGE!

N8N_BASIC_AUTH_USER=user

The password to use for autentication - IMPORTANT ALWAYS CHANGE!

N8N_BASIC_AUTH_PASSWORD=pass

Optional timezone to set which gets used by Cron-Node by default

If not set New York time will be used

GENERIC_TIMEZONE=Somewhere/Nice

The email address to use for the SSL certificate creation

I did try sub-sub folder for the domain and got the certificate working but it still hits page 404.

Not sure where to go from here.

All inputs are much appreciated.

#2

Hi @jay, sorry to hear you’re having trouble! Is the 404 error coming from traefik?

I am asking because your docker compose file doesn’t seem to expose ports 80 (HTTP) and 443 (HTTPS) from traefik, so my first guess would be another web server than traefik answering your browser’s request (and not knowing what to do with it).

#3

Hi there. Appreciate the quick response.

I updated the docker-compose.yml by commenting out the default port, adding loadbalancer for 443 & 80. This time, the favicon shows up on the tab and page indicates “gateway timeout”. So its getting somewhere.

I gave sub sub domain another try with the above changes so that it could work with ssl from traefik, but the ${SUB_SUBDOMAIN}.${SUBDOMAIN}.${DOMAIN_NAME} goes to page 404. env was also changed according to these variations.

When looking at the log, it still seems to default to port 5678 and the same userSettings directory. How can one force those changes?

#4

After having another go at this, i figured out that I had the whole port situation upside down.

Left the default 5678 port on the loadbalancer, added the same network name used by traefik & it worked.

The docker-compose file with sub-sub domain(redacted):

Hi @jay, it looks like your updated docker compose file still doesn’t expose 80s and 443 to your host. So when a request on these ports reaches your server traefik can’t respond to these. If you check the example file from Docker Compose - n8n Documentation you can see the section exposing these ports:

    ports:
      - "80:80"
      - "443:443"
