Connect from and to Horizon client black screen

Hello,

I have a problem connecting from a VMware Horizon client to a other location/company also using VMware Horizon.

When i use mu VDI computer and want to connect to a external company computer that is also a VMware Horizon VDI i get the black screen and after 10 sec i get the time out error.

Anyone know how to solve this problem?

It's often because a firewall between your Horizon client and the Horizon environment has blocked the PCoIP ports (TCP 4172 and/or UDP 4172).

When these ports are blocked, you will get a black screen for a few seconds and then it will fail.

Thank you for the replay.

The strange thing is that is all works when i use a "normal" computer with Horizon client on it.

But when i use a Horizon computer to use the installerd Horizon client to connect to a other Horizon computer i get the black screen.

The reason i do this is because some people work for 2 different company's and want to login to the other location.

But both company's use VMware Horizon.
