Error while trying to donate on my old phone

On old versions of Android (4.1, 4.2, 4.3 etc... for example) Google no more provide the ability to update Google Play Store and Google Play Services apps to the last version compatible. This issue appears if you haven't updated your device for a long time or if you made a factory reset.

To solve this issue you need to manually install (it's called "sideloading") the last version of Google Play and Google Play Services.

Here are the two files to install to update Google Play and Google Play Services. Download them from your phone, then open the download folder and click on them to install them. Note that you may need to enable "Unknown source install" option in your phone to be able to install them. To know how to do that, check this page.

This two apps are safe to use. If they were not official Google apps, your phone would refuse to update the existing version of these apps.

Check your Router

A common issue with the connection is a feature call "Access Point Isolation" (AP isolation) which may be enabled by default on your router. this feature prevent devices connected to the WIFI to connect to other devices on the network. You can check if the feature is available in your Wifi configuration on your router. Sometime, if it's a router provided by your ISP, you can just contact your internet provider and ask to disable the feature.

A simple way to check if Access Point Isolation is enabled is to try to ping your phone. Here is a tutorial on how to do that:
"Pinging" an Android phone means sending a network request to it in order to check whether it's online and to measure the delay in network communication, also known as latency. Here is a step-by-step guide on how to ping an Android device from a Windows computer:

  1. Find the Android device's IP address:
    On your Android device, go to Settings > About phone > Status > IP address. Please note that this path may vary slightly depending on the make and model of your Android device. The IP address will be a series of numbers in the format "192.168.x.x".
  2. Ping the Android device from your Windows computer:
    • Press the Windows + R keys on your keyboard, then type cmd into the Run dialog box and press Enter. This will open the Command Prompt.
    • In the Command Prompt, type ping <your-android-ip-address> and press Enter (replace <your-android-ip-address> with the actual IP address of your Android device).
    • You will see a series of "Reply from..." messages if your Android device is reachable and properly set up to respond to your ping requests. If Isolation is enabled then the phone will not be reachable and you will see messages stating "Destination Host Unreachable" after a few seconds.
Please note that the device you're trying to ping and your Windows computer should be on the same network (connected to the same Wi-Fi, or the same router using wifi or cable). Also, be aware that your device's IP address can change whenever it disconnects and reconnects to the network, or when it moves between different Wi-Fi networks.


Check your Firewall

First of all you need to ensure your network connection location is configured as private network. To do that, follow these instructions. If you use a wired connection, the instructions for you start at the middle of the page.

If it still doesn't work, in windows, go to Control Panel => System and Security => Windows Defender Firewall => Allowed

Then allow Remote System Monitor server like on the picture below


Check your Antivirus

It is possible an Antivirus detect the server as a malware by error. It may happen sometime after  an Antivirus update. Just allow the server in your antivirus and report the server as false positive to your antivirus manufacturer.

  • Restart the server
  • Try to connect again. The SSL error should be gone. However, the Android app will ask you to validate the certificate. It's normal.
