Changing the Domain for n8n on VPS at Hostinger

If you want to use your own domain (or subdomain) for accessing n8n instead of the default srvXXXXX.hstgr.cloud address, you can update the configuration by following these steps:

1. First, please make sure that the n8n subdomain of your desired domain is correctly pointed to your VPS IP address using an A record in your DNS settings.

2. Access your VPS through a browser terminal:

   

3. Navigate to the container directory (replace [container-name] with your actual container’s name):

   cd /docker/[container-name]

4. Edit the environment configuration file by running:

   nano .env

5. Locate the TRAEFIK_HOST value and replace it with your own domain or subdomain that points to your VPS (e.g., sub.domain.com).
6. Save the file by pressing Ctrl+X, then Y, and Enter.
7. Open the docker-compose.yml file and make two changes:
   • Change 1 — Fix the WEBHOOK_URL:

     # Before
     - WEBHOOK_URL=https://${COMPOSE_PROJECT_NAME}.${TRAEFIK_HOST}/
     
     # After
     - WEBHOOK_URL=https://${TRAEFIK_HOST}/

   • Change 2 — Fix the Traefik router rule:

     # Before
     - traefik.http.routers.${COMPOSE_PROJECT_NAME}.rule=Host(`${COMPOSE_PROJECT_NAME}.${TRAEFIK_HOST}`)
     
     # After
     - traefik.http.routers.${COMPOSE_PROJECT_NAME}.rule=Host(`${TRAEFIK_HOST}`)

     

8. Restart the n8n service to apply the changes:

   docker compose down
   docker compose up -d

Once restarted, you should be able to access n8n via your custom domain. Make sure DNS propagation is complete before testing the new address.
