I got this error when I try connect to remote host. The program works with 3 remote machine but I always have the error with 4th remote host.

I have no ideas how to fix the problem. I use libssh2-1.2.4.

Does openssh or other SSH tools connect fine to this 4th remote host?

This error messages comes from src/kex.c:402 in the diffie_hellman_sha1() function when libssh2's sig_verify function fails.

I cannot see why it would not work for any particular host. I would suggest that you enable debugging and fire up your debugger and single-step through this. Unless of course you can tell us a public host that shows this problem...

Oh, and just to be sure that you're not chasing already fixed problems I would suggest you at least first try 1.2.5 or the current git repo to see if the problem persists.
