It is. Your code is only capable of one authentication algorithm out
of the several supported by the protocol.

Learn more about the protocol so that you can make informed decisions
about what parts you must implement and what parts are optional.

Mikhail already pointed out exactly what the problem at hand is, and
libssh2 supports keyboard-interactive without problems. The sftp.c
example is one reference, ssh2.c is another reference. Both implement
keyboard-interactive and ssh2.c is slightly shorter.

There are no issues.

This has nothing to do with the network stack and is a matter of your
client not doing everything neccessary to interoperate correctly with
arbitrary SSH server configurations.
