script crashing after unplugging iPhone from USB

[brokoler]

Hello,

I'm using macOS to run SideJITServer and followed the Youtube tutorials to set it up. SideJITServer was successfully installed via pip install SideJITServer and afterwards my iPhone was paired via USB and sudo SideJITServer -y

Used software versions: This was tested with macOS 14.4.1, iPhone 17.4.1, SideJITServer 1.3.0, pymobiledevice3 3.4.4

Issue description SideJITServer then started and created a USB tunnel, but after unplugging my iPhone when the script is running it crashes completely. Please see following error messages:

During handling of the above exception, another exception occurred:

KeyError: <Epoch.INITIAL: 0>

The error reason seems to be following:
**RuntimeError: qh3 v1.0+ no longer support passing cryptography certificate objects within a QuicConfiguration object. Use configuration.load_cert_chain(...) instead using PEM encoded values.**

**To me it seems something needs to be changed in the script, PEM encoded values seem to be forbidden now.**

i have the same issue and have not found a fix

[fritzlb]

I experienced something similar with pymobiledevice3, running pip install qh3==0.15.1 fixed it :)

[polymo1]

running pip install qh3==0.15.1 fixed it

is qh3 a replacement/alternative to pymobiledevice3?

[fritzlb]

Nope a dependency Older pymobiledevice3 versions don't specify a version of qh3 and the newest release isn't compatible anymore
