Problem: One of my erwin data modelers cannot connect to my mart. I am getting the error:
mart version validation failed. Details: Mart Server is not reachable, please check network and mart server health.
The user was missing a web certificate on the Erwin Data Modeler client machine that was recognized by the Admin Server to complete the connection. The certificate was installed as part of SSL and the need to install it on this PC was somehow forgotten. Once installed on the client PC in question, the erwin client was able to reach the mart admin server. Please check if the mart server is SSL enabled.
