Resolution

On the PC/Portal machine, go to the /opt/CA/PerformanceCenter directory (you may need to go in a different directory if you did not install the PC on the default directory).

Run: ./SsoConfig

Single Sign-On Configuration Tool
Enter q to quit the program or b to go back to previous menu

SSO Configuration:
1. CA Performance Center
Choose an option > 1

SSO Configuration/CA Performance Center:
1. LDAP Authentication
2. SAML2 Authentication
3. Performance Center
4. Single Sign-On
5. Test LDAP
6. Export SAML2 Service Provider Metadata
7. Enable FIPS
8. Performance Center Local Password Authentication
9. Enable or Disable a user account.
Choose an option > 3

In one of the parameters listed (Web Service Host), you should see xxx.yyy.zzz.company.com. Replace with the correct IP address of the PC/Portal machine.

Make sure to use Remote Value so the setting will be pushed to the data source.
