N8N on NAS synology

Hello ,
I have a little question

I have installed n8n with docker and portainer on nas synology. To run n8n I need HTTPS.
I can configure everything and it is working.

My problem is I need to register credential information to connect to google sheet API.

When I try to configure it :
there is an OAuth Redirect URL like below :
https://n8n.MYDOAIN.me/rest/oauth2-credential/callback

I have installed a certificate ssl on domain
https://n8n.MYDOAIN.me to have https but when I try to finish the process I have 404 error.

Do I need to add something in reverse proxy ?

  • n8n version: last
  • Database (default: SQLite): NAS SYNOLOGY
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app): docker
  • Operating system: NAS SYNOLOGY

Hey @Matthieu_Beucher,

Do you have a reverse proxy configured already and have you updated the DNS record for your domain to point to the correct IP?

check control panel/login portal/advanced/reverse proxy, than you can get a certificates from security section on DSM with your domain
