Network error.

[BrusLi44]

First note, this is 100% not a herocraft problem, but a personal one.

I'm receiving this error once I open the launcher. It may be a new error nobody had before , because google couldn't find anything about it so far.

I'd appreciate any sort of help

You have something blocking the port or connection.

The firewall / antivirus maybe ?

I'll try adding minecraft.exe on both of them.

EDIT:
It worked!

Wonder why I haven't thought of that
