AndroMouse server connection errors typically occur when the Android app cannot communicate with the desktop server software due to misconfigured network settings, firewall restrictions, or IP mismatches. 1. Verify Local Network Alignment
Same Wi-Fi: Confirm that your Android device and PC connect to the exact same Wi-Fi network.
No Guest Networks: Avoid connecting either device to a guest network, as these restrict local device-to-device communication.
Disable VPNs: Turn off active VPNs on both your phone and PC, as they mask local IP addresses. 2. Match IP Addresses Manually Automatic discovery often fails on crowded routers.
Find PC IP: Open Command Prompt on Windows, type ipconfig, and look for the IPv4 Address (e.g., 192.168.1.15).
Manual Input: Open the AndroMouse app on your phone, choose Manual Connect, and type your PC’s precise IPv4 address. 3. Configure Windows Firewall
Windows Defender frequently blocks the incoming signals sent by AndroMouse.
Allow the App: Open Control Panel > System and Security > Windows Defender Firewall > Allow an app or feature through Windows Defender Firewall.
Check Permissions: Locate AndroMouse Desktop Server or Java™ Platform SE binary and check both the Private and Public boxes.
Open Ports: If prompted manually, AndroMouse relies on ports 9512 (TCP/UDP) and 9511 (UDP) for discovery. Ensure these are open. 4. Update Java Runtime Environment (JRE) The AndroMouse desktop server runs entirely on Java.
Outdated Java: An outdated Java version causes silent server crashes or socket binding failures.
Fresh Install: Download and install the latest version of the official Java Runtime Environment. 5. Clear App Cache and Restart
Clear Storage: On your Android phone, go to Settings > Apps > AndroMouse > Storage and tap Clear Cache.
