Thanks for the quick answer ! I disconnected my other macbook but still the same problem. In audirvana Audio output, i don’t have any other choice …
Hello,
Any answer for that problem.
Same RED Explanation mark, on both service : Wifi + Ethernet
How to find the other service thaht use Upnp on OS X ?
Thank you
Has anyone found a solution to the problem of ,Error initializing UPnP stack’? It’s totally annoying as it makes AS unusable for weeks on my Mac Mini 2018 running macOS Ventura 13.2.1
That’s what I’m getting
Ok, and you still have the error you mentioned above?
After switching off my MacMini over night, I turned it on again this morning, and, again, sadly, the same error popped up:
Error initializing UPnP stack, error: -203 UPNP_E_SOCKET_BIND
Re-ran the lsof -i 4udp:1900 -sTCP:LISTEN command in terminal, but no success this time: same problem of not connecting to my UPnP devoce.
In addition, every time I switch off my computer and re-start AS, I need to install the SysOptimizer.
It’s getting annoying …
I have the same issue
for those who have the same problem: check your login items (MacOS settings).
most likely you have an app running that already uses the UPnP Port.
for me it was EyeConnect. Disable everything suspicious and reboot.
