Asset often has to be restarted to show up on my WiFi network

[pbarach]

I am running the latest paid version of Asset on a Windows 11 PC that is set up never to go into SLEEP mode. There are times when Asset doesn't show up on the media player on my iPhone (Foobar2000), on the media player in my Denon AVR, and on the media player built into my Oppo 103. In other words, if it's missing from one device, it's missing from all of them. Yet Asset uPnP seems to be running just fine on my PC, and when I restart it, then it shows up on the other devices. Is there some setting I can change to keep it accessible?

It means SSDP is not working correctly on your router:

If SSDP isn't working correctly, is there anything I can do to fix it, other than setting the service to run automatically instead of manually?

It is likely the router

What router do you have and how is your PC connected (is it connected directly to the router or via a swicth, and is so what switch)?
Are your phones connecting to the routers Wi-Fi or do you have additional AP's/mesh system?

Do you have IGMP Snooping/Proxy enabled on your router and switches, and if so, have you tried disabling them?

I have the AT&T 5286AC router, and my PC is connected via WiFi. No additional mesh system or extenders. I see nothing in the router's http pages about IGMP

Try restarting the router, if no go, try updating it to latest firmware, if still no go, try borrowing another router, perhaps use other router as DHCP and forward all internet data out to the old router.
