Hey, I am setting up an n8n node but I can’t add any Google/Slack Oauth because n8n will force me into using umbrel.local for the redirect URL, which obviously won’t work from the outside. I know that N8N gets this from DEVICE_DOMAIN_NAME. How can I change it so that I can use my duckdns domain instead? Should I just change n8n’s docker compose? Or should I update this in Umbrel OS somehow?
Hey, I would change the DEVICE_DOMAIN_NAME environment variable in the Docker Compose file for n8n to your DuckDNS domain and restart the service. This will allow you to use your DuckDNS domain for OAuth redirect URLs.
Also, ensure that your DuckDNS domain points to your server’s public IP.
