RPD 3.7 Content button greyed out and no GAB

In some cases we have a greyed out content and FECC button.

• RPD 3.7 Windows calls a GS310 6.1.2 or Cisco EX 90 content doesn´t work
• GS310 calls RPD it works.
• RPD calls RMX it works.
• RPD calls RPD it works

This issue is noticed after updating to 3.7.

All endpoints are in out local network and are registered in dma 6.1.2 and rm 8.2.1.

Also we can´t access our GAB in RPD Clients after updating to 3.7.

Has anybody the same problems?
