Unknown plugin kcptun

[ghost]

The plugin has been successfully installed.
For profile A and B:

• A can start running with kcptun (although not successful and I'm still debugging with B)
• B cannot start, carrying with an error failed to connect the remote server: Unknown plugin kcptun.

Check your system settings.

You may need this: #12
It requires root permissions

EDIT: found the problem for my case, checking notifications showed shadowsocks needed the permission to run secondary app kcptun. Once I allowed it, working again.

Reproduce.
uninstall and install kcptun. First time shadowsocks+kcptun connection works,
second time, gives error "Unknown plugin kcptun"
Check Notifications shows "Stopped Shadowsocks from launching secondary app kcptun"
when you click kcptun, its asks permission for kcptun to be launched by shadowsocks.
Click allow, and all working again.
