I am trying to create a credential for my cloud self-hosted n8n instance on. OVH Cloud.

**
https://vps-########.vps.ovh.ca/rest/oauth2-credential/callback**
The URI is valid but shows the following error.

Request Id: 624070d5-2c64-4f11-bb96-22a1268e6300
Correlation Id: 4d7d5feb-fcfe-456b-8349-c7312693f003
Timestamp: 2025-11-25T21:04:45Z
Message: AADSTS90102: ‘redirect_uri’ value must be a valid absolute URI.

Any idea of what I should do ? Should I try to change the OAuth Redirect URL of my instance ? Should I try with another URL ? Microsoft are pretty stict with their URI verification but It’s a pretty simple setup so there must be a solution.

Definitely that url isn’t valid.(with a . dot at beginning).

You know your host/domain, soo in your .env file or docker file set the following variables :

N8N_HOST=my-valid-domain.example.com

N8N_EDITOR_BASE_URL=https://my-valid-domain.example.com

WEBHOOK_URL=https://my-valid-domain.example.com

Restart your instance, and after check the URL s .
