Citrix Gateway Services: DaaS control plan, VDA is 2402 CU1. HDX Adaptive Transport, Session Reliability and Rendezvous enabled in Citrix policies (testing against one delivery group). On VDA, the GctRegistration key is set to 1. I've validated the SSL ciphers are present on the VDA. CTXSession -v shows CP > CGP > ICA. I can't get the machine to register to Gateway, it is still registering to our Cloud Connectors. No proxy in place. Is there any log that would show why it is not using Rendezvous?

I assume there is access to these urls The VDA machines must have access to: •

https://*.<http://xendesktop.net|xendesktop.net>

on

TCP 443

. If you can’t allow all subdomains in that manner, you can use

https://<customer_ID>.<http://xendesktop.net|xendesktop.net>

, where <customer_ID> is your Citrix Cloud customer ID as shown in the Citrix Cloud administrator portal. •

https://*.*.<http://nssvc.net|nssvc.net>

on

TCP 443

for the control connection with Gateway Service. •

https://*.*.<http://nssvc.net|nssvc.net>

on

TCP 443

and

UDP 443

for HDX sessions over TCP and EDT, respectively.

Thanks @Rob Zylowski Turns out, it was Cisco Umbrella Agent service. Disabling that, i was able to get Rendezvous 2 working.

Glad you figured it out
