Microsoft RDS RDWEB 2019 html5 Webclient mit Netscaler veröffentlichen

Problem: Neuer RDWeb Client (Microsoft Windows Server 2019) funktioniert mit Veröffentlichung über Citrix Netscaler nicht. https://[name]/RDWeb/Webclient ist erreichbar, funktioniert intern und über NAT aber nicht über den Reverse Proxy (Stellt keinen Inhalt im Browser dar).  
Logs siehe unten.

Andere Leute haben ein ähnliches Problem: https://translate.google.com/translate?sl=auto&tl=en&u=https%3A%2F%2Fsocial.technet.microsoft.com%2FForums%2Fwindowsserver%2Fru-RU%2F96e72f2e-f26f-4057-9835-b414403fe468%2Frds-webclient%3Fforum%3Druwinserver2016
 
Lösung "Websockets" in System > Profiles > HTTP aktivieren (für die Policys, die vom Content Switching Virtual Server verwendet werden). Und schon funktioniert die Remotedesktopverbindung im Browser!
