i doubt if utls's fingerprint has been detected

[Nyx2022]

in some site, when is use utls to imitate browsers like chrome and firefox，but it will has the err:
ReadVersion: expected 'H', got '\x00' at position 0 when receive response
but when i use golang's tls it will not has the error,so i doubt if utls's fingerprint has been detected and be blocked!
