Hi to all.

I’m a very beginner with SC and at the beginning I’ve this problem.
When I try to run the server I’ve this error: ERROR: Primitive ‘_NetAddr_SendMsg’ failed. Below all the messages in the post window:

Booting server ‘localhost’ on address 127.0.0.1:57110.

I’ve tried to kill all server, do a downgrade of SC from 3.11 to 3.10.4, close all the programs, invoke gods, but nothing. I’m going crazy and I don’t understand why I’m getting this error. I’ve asked to my friend who use a lot SC and for him it looks like I’ve some problem with OSC, but searching I didn’t find nothing about it.

Can someone help me?

Ah, I’m on osx 10.14.6.

Thanks to all

Hmm… so, some process on the machine is using that port.

I see that you’ve killed all servers, but perhaps a/ that failed for some reason, or b/ maybe it’s a process totally unrelated to SC (in which case, “Kill all servers” wouldn’t affect it).

For a/, check the system monitor for any leftover scsynth processes (or maybe supernova) and kill them by hand.

For b/, a quick search turned up lsof -i:57110 as a system command (use Terminal) to list processes using that port.

EDIT: One other thought – check that the 3 SC executables (scide, sclang, scsynth) are granted network permissions. If they don’t have network permission, that would explain why both sclang and scsynth failed in the network layer. The scsynth error is common but the sclang error is highly unusual – making me think, maybe the OS is rejecting both processes’ attempts to open a port.

I’m not a Mac user so I’m not sure where to check that or how to solve it – but this does strike me as a plausible explanation (especially if the behavior persists after a reboot).
