Why Am I Receiving an Authentication Failed Error?link
Questionlink
Why am I receiving the following error while setting up the Salesforce connector:
Authentication Failed. Unable to request access information!
Environmentlink
Connector: Salesforce
Resolutionlink
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.
