TDM error: "Failed to connect to DevTest Portal with the provided details. Do you still want to save the configuration"?

Products

• CA Test Data Manager (Data Finder / Grid Tools)

Issue/Introduction

Integrating DevTest and TDM.
Both TDM and DevTest are in the same network and have firewalls disabled.
I was able to ping them, telnet the main ports from each side and open both Portals in both machines.

When I try to configure the DevTest Portal information under the Configuration --> DevTest Portal page in the TDM Portal, the message:
"Failed to connect to DevTest Portal with the provided details. Do you still want to save the configuration"?

I can not proceed after that.
I am using the standard 1507 port for DevTest portal and user admin with admin password.

Environment

Test Data Manager
TDM Portal
Devtest

Cause

Using wrong DevTest port number.

Resolution

The port is not 1507, it should be 1505:

Refer to section "Integration with CA Service Virtualization" in the documentation of the version of TDM you are running.

Additional Information

Even though the Portal itself runs on port 1507, the Portal connects to the Registry via port 1505.
