Running a single Server 2019 RDS w/ all roles assigned on this host. RDP is working and Published Apps via RDWEB (SSO) are working perfectly.
.
I installed the RD Web Client option (HTML 5). It works with IE 11, but will not connect to any other browser (Edge, Chrome, FireFox).
.
Certificate is correct, issued by the internal MS CA.
.
Any idea as to why the other browsers will not connect? Error simply states "Connection Reset"
