If Betternet keeps disconnecting and dropping your connection, first rule out common issues by switching servers and changing protocol (from UDP to TCP/OpenVPN/IKEv2) in the app settings, as unstable server routes often cause sudden drops.
Also check your network — unstable Wi-Fi/mobile data can interrupt the VPN tunnel even when Betternet shows connected.
Make sure your Betternet app is up to date and that your device OS has the latest updates, since compatibility bugs frequently lead to disconnects.
On Windows or Android, turning off battery saver and aggressive data-saving modes can prevent the system from killing the VPN process in the background.
If drops continue, clear the app cache or reinstall Betternet, and test on another network (switch from Wi-Fi to mobile data) to see if the issue is your ISP or local router settings.
These are key solutions that we can offer. If you have more, please share.
