    I don’t think this is because of OpenSSL. To solve this try the following:

    This cleans all the compilation previously done, so might remove problem

    make clean

    If that does not work, download Apache from http://apachemirror.wuchna.com/httpd/httpd-2.4.41.tar.gz

    Download OpenSSL and compile to a different directory.

    ./config –prefix=/u01/openssl1.1.1k/

    compile apache with –with-ssl directives

    -with-ssl=/u01/openssl1.1.1k/
