Kuaimiao VPN won't connect: a practical checklist
Make sure ordinary internet access works, choose a route and connect.
Connect and check
Make sure ordinary internet access works, choose a route and connect. Test the website or app you need. If it fails, record the symptom and try one alternative route.
Compare one change at a time
Use the same device, network and task when comparing routes. Repeat the check instead of judging by one speed result. Distance, congestion and the destination service can all affect your experience.
Make the problem reproducible
Write down your platform, system and app version, network type, route, error text and approximate time. Note whether all sites fail or just one. This is more useful than a screenshot saying only that the VPN is connected.
