Something is broken, masternodes aren't receiving any reward anymore.
Suggested that you use the depends compilation method via the source, otherwise a mismatched version of OpenSSL will cause errors with signatures with this ancient software.
e.g.
(via Docker Debian:buster for best results)
git clone ...
cd depends
make
cd ..
./autogen.sh
./configure --prefix=`pwd`/depends/x86_64-pc-linux-gnu (or whatever host you built it for)
make
Thank you but this has nothing to do with the masternodes not receiving any rewards on the blockchain.
