Dev’s should really take a note, the only solution at the moment to run a Linux Client is running the XP Version with Wine, as the HTML5 Version still lacks keyboard support! It’s really time to bring a Linux Version, maybe a “Wine port” would already do the job well!
Which Version did you try?
I am currently running 0932 x86_64 and also x32 0932 is working on wine 6.3 using PlayOnLinux, currently i set the Windows-Version to Windows 10 in Controlpanel of Wine. Whenever i had your message in the past, it was network-related like a firewall, also as it does not find your primary machine, i assume a firewall on that Primary Windows Machine blocks it
Well, you should have read the Title of this Thread 😉 “Spacedesk Viewer on Linux” so only the Viewer works in Wine, the Driver will probably never run in Wine -> as would need to have some really special X-hooks.
