Using html5 Portal for RDP not working with RDP Farm?!

Hi all,

we moved our Terminalserver from 2012 to 2019 Server and also extended to a RDP session host farm.

It seems that the html5 Portal only works if the session broker chooses itself for session hosting. Otherwise only "Socket broken" is shown up.

It should work in general or not?

Thanks for hints
