Cannot connect to steam servers / can't pair
Steam Link was working perfectly on my setup until just a few days ago. It is specific to my MacOS running Big Sur. I know because steam link works on my iphone, apple tv, and android systems pairing to the same machine.

On my Mac, even if I uninstall Steam Link it tries to connect to the PC that it remembers. It doesn't find any computers running steam when I try to scan, and when I click "other computer" it says can't pair / cannot connect to steam servers. I've tried restarting, reinstalling, clearing cache.

Any help would be appreciated

Same for me but the issue is:
Streaming error: Couldn't Connect to PC_IP:27032 (or 27031)

Windows Defender just had a update.. all my ports are open and even changed network config to private. Help Steam!

Steam Link is now crashing regularly. It will just happen at an indeterminate interval. Sometimes within a few minutes, sometimes longer.


ChatGPT extracted this from my crash log:

What matters most in your log
• It crashed on the main thread (UI thread)
Crashed Thread: 0 MainThrd means this happened during normal app logic, not some background worker.
• The specific failure
EXC_BAD_ACCESS (SIGSEGV) + KERN_INVALID_ADDRESS means: “the app touched memory it should not touch.”
• The smoking gun line
Application Specific Information: objc_msgSend() selector name: state
On macOS, objc_msgSend is how Objective C calls methods. This says Steam Link tried to do something like:
someObject.state
but someObject was not a valid object at that moment.
• Where it happened
The top of the stack is:
• libobjc.A.dylib objc_msgSend
• then several frames inside com.valvesoftware.SteamLink17
