OpenSSL 1.1.1c too recent
OpenSSL update to version 1.1.1c may cause problems with other software.
dcdb/install/lib is in
LD_LIBRARY_PATH (e.g. by sourcing
dcdb/install/dcdb.bash), dcdb's bleeding edge OpenSSL library may be used instead of built in OpenSSL. This can cause issues with other software which rely on older/custom OpenSSL versions which still support protocols like SSLv3.
Immediate solution: clear dcdb's install directory from
LD_LIBRARY_PATH (e.g. by opening a new terminal)
Long-term solution: wait until other software supports more recent OpenSSL libraries.
