[winswitch] HTML5 Server throws an Error code 400 XPRA 4.1.1 on Linux DietPi 4.19.0-14-amd64 #1 SMP Debian 4.19.171-2 (2021-01-30) x86_64 GNU/Linux

Hi XPRA Team and Enthusiasts

I love XPRA and want to have one on my own server.


System:
XPRA 4.1.1 on Linux DietPi 4.19.0-14-amd64 #1 SMP Debian 4.19.171-2 (2021-01-30) x86_64 GNU/Linux
Debian 10 Buster as base system

Command starting Xpra:
xpra start :102 --start-child=xterm --exit-with-children --bind-tcp=0.0.0.0:2017 --html=on --mdns=no --webcam=no

Connection using the current XPRA client from Linux or Windows works without issues.



When trying to use the HTML5 server I am confronted with this error message:

Server Error

Error code 400.

Message: this port does not support HTTP requests.

Error code explanation: 400 = Bad request syntax or unsupported method.


I am at a loss what to try next to solve it.

Having "my session" in a browser (secured via SSH port forwarding) is a fantastic feature.


Thank you for an exceptional piece of productivity enhancing software!


Cheers,

Georg
