Error Code 121

Happens most of the time when I try to pair, it only successfully created a server like 2 out of 15 times I tried.

i have the exact same issue, and the only thing i can see between us is that we are both using python 3.12, ill try downgrading really quickly

edit: it seems like there is an error trying to establish an asynchronous connection using asyncio this could be due to network latency or a failure with the tunneling service. it could also be a firewall issue, but that didnt fix the problem for me

edit 2: a consistent way that i found was to wait for the phone symbol to show up in itunes (ie. device connects to your pc), then start the server

edit 3: final fix: at least the way that i have it set up, i have a folder on my desktop in which i cloned the repo. i then created a venv and installed the dependencies as normal. whenever i launch the server, i open itunes and wait for my device to appear. i then double click on my folder and open it. i do alt+f then i press s and then a. this opens an admin powershell window. in the powershell, i check to see that the directory is the one i cloned the repo in. then i do not enter the venv, and instead i just run the command SideJITServer.exe. for some reason, doing it this way seems more consistent.

edit 4: i lied, its still inconsistent

Exactly the same problem, have you been able to solve it?
