Postup řešení

1. 1 Press Windows key + S, type 'Device Manager', and open it. Look for any devices with a yellow exclamation mark. These indicate driver problems. Right-click the problematic device and select 'Update driver'. Choose 'Search automatically for drivers'. This updates the driver to a version Windows trusts, which may resolve the data rejection.
2. 2 Press Windows key + R, type 'eventvwr.msc', and press Enter. In Event Viewer, go to Windows Logs → System. Look for errors with the source 'Tcpip' or 'NDIS' around the time the error occurred. Note the details. This helps identify if a network driver is sending malformed data.
3. 3 Open Command Prompt as Administrator (Win+X → Terminal (Admin)). Type 'netsh winsock reset' and press Enter. Then type 'netsh int ip reset' and press Enter. These commands reset network protocols to default, which can fix data acceptance issues in network drivers.
4. 4 Restart your PC. After reboot, test if the error occurs. If it does, run 'sfc /scannow' and 'DISM /Online /Cleanup-Image /RestoreHealth' as described in the previous guide to repair system files.
5. 5 If the error is tied to a specific application, try reinstalling that application. Uninstall it via Settings → Apps → Installed apps, then download the latest version from the official website.
