Hi Juned,
I am sorry to hear about your trouble.
Please try this:
- Run CMD as an administrator or open CMD – Command Prompt (Admin) by going to Start > type in the search bar "CMD" and then right click > Run as Administrator
A window will open, type these entries one by one after pressing "Enter" on the keyboard for each entry.
- ipconfig /release
- ipconfig /all
- ipconfig /flushdns
- ipconfig /renew
- netsh int ip set dns
- netsh winsock reset
Then, restart your computer. I hope this helps!
Regards,
Ryan
