Hello, thank you for this amazing piece of software. It works well on PC, but fails to run on Termux with the following error:

However, version v1.0.5 seems to work without any problems UPD: v1.0.7 is the latest version, that runs without this error

Confirmed still an issue. I believe it has to do with https://github.com/whyvl/wireproxy/commit/a6797166eba8cfd77de54e8ede1051a9bf4baeee

Namely few if any Android kernels support Landlock so it causes a panic. I did do a test commenting out the landlock calls and version 1.0.8 does work as expected.

A solution may be to add a flag to selectively disable landlock in an unsupported environment (although this is sub-ideal).
