Sudden cannot detect Primary Machine

#1 · 15/06/2026, 03:23

Ive been using spacedesk for about a month from my windows computer to my macbook. Ive had no problems with connecting in that time. Suddenly, my macbook app will say that it cannot detect any primary machine. Ive tried everything, making sure the spacedesk is “ON”, same network, no apps running in the back, restarted/full reboot/installed and uninstalled, and nothing is working. Some help would be appreciated!!
