Hey guys. So I'll confirm for you that Tera1 clients break with Horizon Agent 7.7 or higher.
The problem is that the Tera1 client has a problem setting up the SSL connection to the Horizon Agent on port 4172 after it received the Server Hello SSL packet.
The issue seems to be that Horizon 7.7 creates a self-signed certificates using SHA-256. Of course, Tera1 only knows how to handle SHA-1.
I may not have a resolution for this anytime soon, but attached are two packet captures; one to Horizon 7.6 and another to Horizon 7.7 for you to compare.
