Is this a persistent VM? If so can you remove it from Horizon View shut it down and re-add it to Horizon View and let Horizon View power it on.
Find. I have in pae-MSGSecOption keySize=2048, but with this params horiozn 7.8 in Trace Agent show error, even in clean new installion
The security strength of SHA-1 digest algorithm is not sufficient for this key size
and questions for VmWare: Why in 2019 you are using SHA-1 for new client, and you write, that in enhanced recomended keySize=2048, but with this options agent not working.
After I on test server change keySize to 1024, do resetkey, agent connecting to Server
