Hi Arnab, my name is John D. an independent advisor happy to help you with this.
I understand that you're having trouble connecting to certain websites like Google, Bing, and YouTube.
Here are some troubleshooting steps that you can try:
> Check your internet connection and clear your browser cache and cookies.
> Disable any VPN or proxy software and check your firewall and antivirus settings.
> Try using a different DNS server like Google Public DNS or OpenDNS.
If you're on a corporate or school network, it's possible that there's a group policy set by your network administrator that's forcing the proxy settings. Unfortunately, in that case, you may not be able to change the proxy settings.
If you have any further questions or concerns, please let me know.
Best regards,
John D.
