Horizon client connectivity to the VDI's is failing from the internet. PCOIP and HTML access is working fine.
Do you have the correct ports open on your firewall?
Yes.I have tried with firewall being disabled.
sound like a firewall block issue
worth a test

All required ports are open still the VDI connections externally especially the HTML connections fail with the error "The remote connection to the desktop has ended".
Sounds like a firewall port issue to me. Make sure 8443, 22443 is open between the brokers, the VM VLAN(s) and your access points on the DMZ. Also make sure to follow this KB for your HTML access to work properly VMware Knowledge Base as well as Allow HTML Access Through a Load Balancer , and Allow HTML Access Through a Gateway
Hope that helps. Any of these steps are missed, your connections will failed.
