I don't know if this helps any. I make a successful connection. I have an older version of Open SSH 8.6p1 vs 9.0p1
For some of my older OpenVMS systems I do have to specify specific algorithms.
Host asimov
HostName asimov.xxxxxxxx.xxx
KexAlgorithms +diffie-hellman-group1-sha1
HostKeyAlgorithms +ssh-dss
Ciphers aes128-cbc
But nothing special for eisner
Host eisner
HostName eisner.decus.org
Port 22867
User reinhardt
