You say that, but the evidence suggests otherwise. In each of
whatever shells you're using to start the client and server,
it would be prudent to run:
$ openssl version -v
Here's an example with the command and library at the same version:
$ /usr/local/bin/openssl version -v
OpenSSL 1.1.1c 28 May 2019
And here's another where they differ in the patchlevel:
$ LD_PRELOAD=/lib/libcrypto.so.111:/usr/lib/libssl.so.111 /usr/local/bin/openssl version -v
OpenSSL 1.1.1c 28 May 2019 (Library: OpenSSL 1.1.1a-freebsd 20 Nov 2018)
Without forcing anything with LD_PRELOAD, ... are your client and
server in fact 1.1.1 in both the executable and the library?
