The following error message appears during the opening a published resource in a web browser with Remote Application Server HTML(RAS HTML5):
"The connection was ended because of a network error. Please try to connecting to a remote computer again. (0x87650000) "
The WebSocket header is blocked by a hardware/software router or firewall. A debug console shows the next entry:
It's possible to verify by opening a published application or remote desktop and pressing in a browser F12> Network tab> WS> RDP.
In order to solve the issue,
RAS HTML5 uses the next protocols: WS, WSS, HTTP/1.1
NOTE: Using WS does not mean that a connection is not secure. RAS HTML5 always redirects WS/HTTP to WSS/HTTPS.
When filtering rules are enabled the code '404' will change to '101' and 'Response Headers' will contain a hash.
