There are many solutions when a particular website does not open in a computer. When I faced this problem on my PC, I solved this by checking and correcting my windows hosts file.
For doing this, open your windows host file located at C:Windowssystem32driversetc folder. After opening this file, see whether there is any blocked list defined at the bottom. The format is like this ‘127.0.0.1 www.domain.com domain.com’.
If you find any domain or ip is listed here, then remove that. And your particular website will open again.
Hope this will help if you have problems with your hosts file. Good luck!
