Username and Password login

On my own environment im trying to login to my Mobile App development and an error arises with an message quoting "Request failed with an error". 

Do you need a secure connection like VPN to reach the environment? 

Can you be more specific? So you can't log into your own environment or in your Mobile app? 

If you can not log in to your mobile app, you can read a more detailed description of the error in the Error Log (ServiceCenter).

Your environment is on-premise or cloud? Is it behind a firewall?  This kind of message could be because your mobile app is not reaching your outsystems server.
