Hey @igortsev,

Do you see any errors in the docker logs?

[igortsev]

N8N_LOG_LEVEL:= 'info,warn,error,verbose,debug' - all clear, docker logs clear too. Just working after container restart. Tested that issue with 1.36.X with Docker compose Linux (Ubuntu22)/Windows 11. Just run and leave it ti 20 minutes and you wiil not open dashboard. Tested with localhost and VPS with HOST

Hey @igortsev,

I am not able to reproduce this, What I did was...

1. Went to Digital Ocean
2. Created a droplet based on their Docker Image
3. Updated DNS for n8n.my-testingdomain.com to point to the IP of the droplet
4. Added an n8n user and gave it sudo and docker access
5. Opened ports 80 and 443 on the firewall through ufw
6. Pased in your compose file and added the version line that was missing
7. Created 3 volumes based on your file (postgres_data, n8n_data, traefik_data)
8. Created a .env file that contained the below

# The top level domain to serve from
DOMAIN_NAME=my-testing-domain.com

# 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://n8n.example.com

# Optional timezone to set which gets used by Cron-Node by default
# If not set New York time will be used
GENERIC_TIMEZONE=Europe/London

# The email address to use for the SSL certificate creation
[email protected]

# Postgres
POSTGRES_PORT=5432
POSTGRES_DB=n8ndb
POSTGRES_USER=n8nuser
POSTGRES_PASSWORD=n8npass

I then ran docker compose up -d followed by docker compose logs -f so I could see what was happening

Gave it a few seconds then I loaded the page in my browser and completed the setup like normal.

As this appears to be working fine I suspect there was an issue on your first run maybe with the database or traefik validating the email address for the SSL cert.

Are you able to provide detailed steps on how to reproduce the issue?

Moving to closed for now until we have a way to reproduce.
