@richa_kapoorIf you have a network or system administrator in your office then they must be able to help you with. If a website is blocked by your firewall you won't be able to access it. This is why you have firewall in place. There are different way to access it however not recommended as mostly hackers use them or it was use to hide your identity.
If for some reason you are not able to browse one of your project website then possibly your IP might have got blacklisted by the hosting provider. You would need to connect with hosting provider and get your IP whitelisted. This must solve your issue in case you are able to browse the same website from outside of your office network too.
