A few months after publishing the app, Google marked it as harmful/PUP/malware app. I suspect it's because there's some Google watchdog that sniffed the traffic and found something harmful that was being transmitted by some of the users. Or it's possible that the behavior of the traffic being unencrypted and routed to a single server was similar to typical harmful app behavior that come across Google in the Play Store. There are also a few AVs that have marked the tunneling client fast revers proxy, as a PUP, and it's possible Google Play Store did the same. I've made some mitigations against this by changing the binaries to change the hash, but I suspect Google will still mark it as harmful by reading the strings, so you will need to disable Play Protect, otherwise, the app will likely get automatically deleted.

Make sure you're using the correct port value, then exit the app and start it again. There's a very small chance you used an already used port.

Exit the app and start it again. If it still doesn't work, make sure the app is still running on your device. Then please tweet @Proxidizehq and we'll take a look or open an issue on GitHub.

The app uses reverse proxies created via websockets route to forwarding facing proxies. This technology is slow, unreliable and there's nothing I can do about it with the limited time that I have to work on this project. Apps based on this specific tunneling technology were created for simple IoT use cases, and not for pushing full bandwidth or proxies. The Proxidize team is working on an entirely new app called Proxidize Portable, which will address all the short comings of this app using proprietary technology. Another thing is such apps send both incoming and outgoing traffic from the same device, which means you will always get half the speed that you would normally get when testing the speed directly on your phone. If speed is important, you should use the full Proxidize MPM-OP: https://proxidize.com/

Make sure you're not mixing the small l with a capital I.

This app will work everywhere, unless: You are in countries that have ISP-level firewalls that block any proxied connections via DPI. You are behind a corporate firewall that blocks unknown ports.
