while connect my destination server by

ssh2_connect("<<server-ip>>", 22)

then received error

ssh2_connect(): error starting up ssh connection(-5): unable to exchange encryption keys

ssh2 extention and lib2ssh 1.8.0 already installed

how to resolve this issue?

Does any library need to be added or updated?
