p0f-socket is missing

Hello, can you help me, please?
I've installed your script on my server and I've tried to run it with such command ./p0f-client /opt/p0f-mtu/p0f-socket <ip_adress> but getting such error

[-] SYSTEM ERROR : Can't connect to API socket.
        Location : main(), p0f-client.c:128
      OS message : No such file or directory

also, I've tried "p0f-mtu-script" source code and all I get is
PTR test = Probably home user Fingerprint and OS match. No proxy detected (this test does not include headers detection). No OpenVPN detected.
but nothing about Detected OS

No matching host in p0f cache. That's all we know.

Getting your NTLM hash…

[+] Listening on API socket 'p0f-socket' (max 20 clients).

Не определят OS

Не всегда определят OS через мобильный интеренет, тестировал на андроиде и ифоне (browserleaks также показывает). А если уехать в другой город то определяет корректно. Если выйти в интернет через вай-фай с телефона то OS на этом же телефоне корректно показывает на разных провайдерах.
А как можно подменить фингерпринт?
