Why Am I Receiving an Authentication Failed Error?link
Why am I receiving the following error while setting up the Salesforce connector:
Authentication Failed. Unable to request access information!
Use our Salesforce Sandbox connector instead of the Salesforce connector. For more information, see our Salesforce setup guide.
Fivetran connects to Salesforce through the
login.salesforce.com domain. If you want to use a custom domain, you must use our Salesforce Sandbox connector.
