[zeromq-dev] Building & using ZeroMQ with Visual Studio

[Matt Bolger]

Brilliant! This hard codded port is the culprit.

I'd tested this on two machines but turns out both are running RealVNC
which uses port 5905 for its server.

Also found that this value is hard coded in signaler.cpp in addition to
config.hpp

So the next question, shouldn't this port being in use be handled more
gracefully? Something for me to raise as a GitHub issue I guess?

Thanks
Matt
