Unable to Negotiate Due to No Matching Host Key Type Found Error

Applies to: TCPIP 5.7 SSH.COM Server

SSH connections to a TCPIP 5.7 server may fail with the following error:

debug2: host key algorithms: ssh-dss

debug1: kex: host key algorithm: (no match)
Unable to negotiate with X.X.X.X port 22: no matching host key type found. 
Their offer: ssh-dss

This commonly occurs when a newer OpenSSH client connects to a TCPIP 5.7 server that offers only a DSA (ssh-dss) host key.
