I am currently trying to provide an out-of-the-box DEB installation of
x2gohtmlclient. For this, I need to make some adjustments, mainly
these are about wss: traffic becoming optional and defaulting
everything to localhost with ws: protocol. Of course, in real world
deployments, this needs to SSL'ified again. But I'd really love to
provide DEBs that demo x2gohtmlclient out-of-the-box (and SSL
certificates are not so much things that come out of the box).
This all seems to work fine, only that I get a failure when
x2goclient.min.js starts communicating with the x2gokdrive Xserver
(via x2gowswrapper, via websockify).
I think that my seen bug is caused by my websockify 0.9 which has the
text data mode removed (compared to earlier versions). See:
https://github.com/novnc/websockify/issues/365#issuecomment-432270758
As I am testing everything on Debian 11, I indeed have websockify 0.9
installed. Where did you test the whole stack of x2gohtmlclient,
x2goclient.min.js, x2gowebrpc and x2gowswrapper on? Debian 10, maybe?
My symptom in the browser is:
- Logon works
- X2Go KDrive sessions starts in the background (processes come up, desktop is resumable via native X2Go Client later on)
- X2Go Logo appears in the placeholder area in the webbrowser
- X2Go session strings is shown at the top of the session window in the browser
- and then, the session is immediately closed again.
The (error) message(s) I get in the browser console while this happens
are/is these/this:

Before I dig any deeper, could you try your test setups with
websockify 0.9 and report back if you see a similar error popping up
or not?
Thanks, Mike
