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
OK. Mine is working fine via this method. Enjoy your day.
Thank you but this has nothing to do with the masternodes not receiving any rewards on the blockchain.
