• Option 1: Check if your internet actually has internet. 
• Option 2: In many cases, the wifi device (router) might just need a quick restart.
• Option 3: Your iOS device came from sleep mode so the app will need 15-30 seconds to connect on it's own. If you can't wait, double tap the home button and swipe up to close it. Open SeriousMD again.
• Option 4: You did not update to the latest version yet.
• Option 5: Take a screenshot of your screen and send it to support for troubleshooting.
