Cause

This issue happens when the Archer Workflow Service becomes unavailable or unreachable.

Resolution

Restart the Archer Workflow Service and ensure that the Advanced Workflow URL (shown below) is reachable from all servers as well as outside the server.
If it is reachable, the message Endpoint not found. should be returned in the browser (as shown below).

[Advanced Workflow URL and Port from ACP]/wpservices/rest/auth
