Firewall exception for MoBro
Sometimes devices cannot connect to MoBro due to settings of your firewall. Adding MoBro as an exception to your firewall should solve the issue. Search for "Allow an app through windows firewall" in your windows search bar. Then click "Allow another app" and search in the browser for the exe. The path is "<Drive>:\Users\<youruser>\AppData\Local\". Add it to your firewall exceptions and your devices should be able to connect afterwards.
