I set the CURLOPT_VERBOSE 1 and run test code.
It says "Failure establishing ssh session". I find it in ssh.c .It call the libssh2_session_startup() and return a value .

Maybe you are right. The libssh2's libssh2_session_handshake(x,y) cause the code 2.


How to fix it ? Can you give me some advice?Thank you

Yes, and now you only need to start learning how not to top-post:

If I had known the answer I wouldn't have asked you. You should debug this
case. Single-step into libcurl and see what internal call makes it return a
failed init. It is a rather early fail and there's not a lot of places that
_can_ reeturn that code so it shouldn't be that deep or strange.

I suspect a third party library failure somehow.
