Hi everyone,
I’m having trouble connecting Salesforce to n8n Cloud. I can’t link my account and always end up with an OAuth error.
Describe the problem/error/question
When I try to connect Salesforce via n8n, I get the following message:
OAUTH_APPROVAL_ERROR_GENERIC : An unexpected error has occurred during authentication. Please try again.
Here’s what I’ve already tried:
-
Logging in via our SSO → failed
-
Logging in with our domain name → failed
-
Tried both Production and Sandbox → same issue
-
Signed out/in from Salesforce before connecting via n8n → no change
-
Private browsing and without VPN → no change
-
Removed and recreated the Salesforce credentials in n8n → still fails
My workflow (simplified)
- Schedule Trigger → Salesforce (Get Many Accounts)
The Salesforce node fails right at the connection step.
What is the error message (if any)?
OAuth Error Salesforce: “We can’t authorize you because of an OAuth error.”
