Salesforce Connector - DCM.E Connection error

[suarezr]

My Server and Designer were recently upgraded to 2024.2.
Salesforce Connectors are on version 5.1.4

Post-upgrade, any workflow run on the server runs into an error on the Salesforce connectors tool(s), but the same error does not occur when I run the workflow locally in Designer. The firewall allow list is setup the same as pre-upgrade, and a ping test to the salesforce domain is successful. Anyone know the cause of the error?

Error Message: 

DCM.E: Failed to obtain connection information for: {'message': 'Missing object.', 'detail': 'The connection could not be found.', 'errorCode': 1002.0, 'dcme_exception': DcmEException('Dcm.E Error!')}.
