To use the Mobile app, you need to enable the Cloud subdomain and connect to the subdomain.
However, there is a way to use Mobile app and Mobile card with internal network only. The subdomain method uses the Cloud API, but is available using the Local API 2.5 or later.
After creating the server in the Local API, enter the cloud address (instead of https://api.biostar2.com).
* Note: Please use http on Local API Server. https is not supported on mobile app when you use Local API.
