Hi,

On one of our servers, we can successfully connect to the given server via "normal" SSH but for some reason it doesn't work with phpseclib. The issue occurs only on one of our servers. On other servers, with the same versions for the OS and sshd, the connection via phpseclib runs flawlessly.

Here is the NET_SSH2_LOGGING output:
