25.3.1 netbsd; scp tramp has long delay on first connection

[Van L]

Hello,

Using emacs to list a directory on a remote machine takes longer than expected.

I can ssh immediately but emacs’s tramp delays are over 60 seconds for the 
first time connection.

Is there a setting that is needed? Going in the other direction on the network 
with 26.1 emacs connects immediately.
