Looks like you neglected to build psql with OpenSSL support,
and the server is insisting on having an SSL connection.

Ok, that makes sense.  Attempting the below, but receiving this error:

./configure --without-readline --with-includes=/usr/lib --with-openssl

checking for CRYPTO_new_ex_data in -lcrypto... no
configure: error: library 'crypto' is required for OpenSSL

[postgres@servername postgresql-14.2]$ ls -lhrt /usr/lib/*crypt*
-rwxr-xr-x 1 root root 547K Feb 28  2017 /usr/lib/libgcrypt.so.11.8.2
