I would be more than happy to work with a Network Engineer to resolve this issue. This affects many people at work as well as vendors who use AT&T hotspots to connect to our resources. Funny how VMware and AT&T Business are supposed to be helping customers and businesses work, and then this happens. Either by a direct firewall deny policy or by not allowing the needed services/ports/applications in the firewalls that Horizon View requires. This is AT&T blocking the VM workstation/service tunnel/proxy/port(s). If I am using a Frontier DSL connection, I have no issues. If I use a Verizon hotspot or my work phone on Verizon (Android Client for Horizon), I have no issues.

I have tried with both VMBlast and PCoIP protocols, and the same issue occurs if I try to use a web browser and the html5 option. This IS AT&T blocking the tunnel/proxy/port(s). I can connect to the Horizon View server, but as soon as I try to connect to a service or a VM desktop it always fails. My employer uses VMware Horizon View for remote access to VM workstations and services. It would be good to know if this is a regional firewall issue or a national one.

This is affecting me, in the greater Seattle area. This is STILL an ongoing issue with AT&T wireless and connecting to VMware Horizon View services (NOT the initial connection to the server). I saw a few specific posts (regarding a certain model of hotspot), and posted in that thread, but then thought this should be a new topic not tied to a specific hotspot.
