Fix #4: Flush DNS and Reset Network Adapter

Network glitches? Time to flush them out! DNS errors often masquerade as connection aborted problems.

Run these in an elevated Command Prompt:

1. ipconfig /flushdns
2. ipconfig /release
3. ipconfig /renew
4. netsh int ip reset
5. netsh winsock reset

Then, restart your PC. To sweeten the deal, switch to public DNS like Google's (8.8.8.8 and 8.8.4.4):

2. Go to Change adapter options, right-click your connection > Properties.
3. Select Internet Protocol Version 4 (TCP/IPv4) > Properties.
4. Enter the DNS addresses and save.

This combo has saved countless update sessions. If you're still stuck, the next section has a powerhouse solution. ⭐
