Postup řešení

  1. 1 Check your internet stability by running 'ping -t google.com' in Command Prompt for a minute. If you see high latency or packet loss, your connection is unstable. Restart your router and try again.
  2. 2 If you're using a VPN, disconnect and try without it. VPNs can cause connections to drop.
  3. 3 Press Windows key + X and select 'Network Connections'. Right-click your active connection and select 'Properties'. Select 'Internet Protocol Version 4 (TCP/IPv4)' and click 'Properties'. Ensure 'Obtain an IP address automatically' and 'Obtain DNS server address automatically' are selected. This ensures your network settings are correct.
  4. 4 Open Command Prompt as admin and run 'netsh int tcp set global autotuninglevel=normal' to reset TCP auto-tuning, which can improve connection stability.
  5. 5 Restart your PC and try the operation again.
