Hi Mike, I'm using at the moment HTML Client on Debian 10, RH-7, Cent-OS7. I'll try to upgrade my development system to Bullseye and will let you know how it works. I never tried this setup without using SSL and I can imagine that there's could be some security restrictions in browser, which makes it impossible. Anyway, I'm going to try it and will come back to you.
regards, Alex PS: Don't think the reason is the text mode, because client opens socket in binary mode. Anyway, I will get rid of websockify and put the ws support into x2gowswrapper code Am 21.06.21 um 10:13 schrieb Mike Gabriel: > Hi Alex, > > On Mi 21 Apr 2021 22:43:53 CEST, Oleksandr Shneyder wrote: > >> https://wiki.x2go.org/doku.php/wiki:advanced:x2gohtmlclient > > I am currently trying to provide an out-of-the-box DEB installation of > x2gohtmlclient.
