--- Comment #1 from Darren Tucker <dtucker at dtucker.net> ---
OpenSSL changed their binary compatibility policy between 1.1 and 3.x
series, but we didn't notice that for a while.

We updated our compat checking code in
https://github.com/openssh/openssh-portable/commit/b7afd8a4ecaca8afd3179b55e9db79c0ff210237
 which was first in the 9.4p1 release.  You're using a version older
than that, which incorrectly applies the 1.1.x policy to the 3.x
series.

If you are using a vendor-supplied OpenSSH binary, you'll need to talk
to them about backporting and/or rebuilding.  If you're using a binary
you built yourself, you'll need to either rebuild, backport the patch
and rebuild, or update to a newer version and rebuild.  There's nothing
that we can do that we have not already done.
