Hi jcuypers,
I have the same issues. This is in regards to trying to connect Google Cloud OAuth2 with the Google node. My specific issue was trying to connect Google Docs node using OAuth2. After setting up Google Cloud credentials and inputing the Client ID and Client Secret, I was prompted to “Sign in with Google”. After attempting to sign in with google I was immediately hit with the same message as fernando. Seems to be a very common issue and I have not found a work around
Same identical issue here.
I am running n8n locally on a Raspberry PI with private IP but I access the n8n GUI via a Cloudflare tunnel via a custom subdomain which is what I’ve used to add to the Authorised redirect URIs in the OAuth Client ID for Web application config.
Just to reply to myself and perhaps might help others, I have setup the WEBHOOK_URL environment variable with my subdomain as per Securely Self-Hosting n8n with Docker & Cloudflare Tunnel (The... Arguably Less-Painful Way) and that helped.
Hi Fernando,
The issue is due to a redirect URI mismatch. To resolve it:
