Infuse will not wake iMac anymore

hi,

not sure it it’s since I updated to Monterey, to tv0s 15.2, or latest infuse but I can never connect anymore on my iMac. I’ve tried to manually wake up the hard drive, to force close infuse on Apple TV, to reboot Apple TV, and the only thing that works is a reboot of the iMac. then after infuse sees my shared folders… any ideas why? it used to work all the time…
