Describe the problem/error/question
Hey everyone, I’m stuck with a Google OAuth issue on n8n Cloud and would really appreciate some help.
What I’ve confirmed OAuth Client ID in n8n matches exactly the one in Google Cloud OAuth client type is Web application Authorized redirect URIs
Google Drive API is enabled OAuth consent screen is configured correctly Credentials recreated in n8n Tested in incognito + different browsers Despite all of this, Google still returns redirect_uri_mismatch. Question Is there any known issue with n8n Cloud where the OAuth redirect URI differs internally from what’s shown in the UI, or requires an additional domain (e.g. oauth.n8n.cloud) to be registered?
I have tried everything possible when i sign in with gmail and press go to cloud(unsafe) i then select all on what n8n has access too then im met with A white error page that says Error: Bad Request More details {“error”:“redirect_uri_mismatch”,“error_description”:“Bad Request”} Failed to connect. The window can be closed now or Error: The OAuth callback state is invalid! i swear i have the correct redirect URL in google cloud More details Failed to connect. The window can be closed now. Happy to provide logs or screenshots if needed. Thanks in advance 
!
What is the error message (if any)?
{“error”:“redirect_uri_mismatch”,“error_description”:“Bad Request”} Failed to connect. The window can be closed now or Error: The OAuth callback state is invalid! i swear i have the correct redirect URL in google cloud More details Failed to connect.
