After testing the new Mendix Version with a Native App I had to recognize that this error message always shows up. I haven’t changed anything in comparison to the older versions… Does anyone else have a problem with the new version in combination with the “Make it Native” App? PS: If I click the “Reload” button the MiN App is loading from the Port 8083 instead of the set Port 8080, obviously the next error is “Could not connect to a deployment server”. I also changed the set Port to 8083, after I tried that the MiN App crashed.
This error occurs because of your desktops or laptops firewall. Not recommended but disable your all firewalls on your PC for a while and then try to relaunch Mendix Make it native app. Hope fully it should connect now.
