[Gokulkannan]

Hello,

I am using Horizon connection server version 7.10.0. I use to connect VDI in default Blast protocol. recently I upgraded Horizon client 8.7.0. After that I getting Black screen , while connect VDI. If I change Pcoip from desktop Pool , I can able to connect VDI . Anyone experiencing black screen issue after upgrade Horizon client 8.7.0?

For me In many situation the problems were tcp ports blocked 

But you can check this guide:

Could you please upload client debug log so that I can check the root cause? Thanks.
