If you're having trouble connecting to the miniExtensions server, there could be several possible reasons for this issue:

Our app is hosted on Google Cloud and Google is blocked in China. In this case, you can use a VPN to get around the firewall. That's all we can suggest.

If the link opens fine on your computer, but you get an error message on your phone (or vice versa) then most likely the problem is within your device configurations. Check what could be blocking the connection in your browser settings, VPN, or ad-blocker. Try using another device/network and see if the problem persists.
