Sitecore login page error : No such host is known


Dear Readers, Apologize for not sharing anything with you since so long. As was bit busy with projects. (But It’s good to be busy. Because during your busy time you learn a lot, and needless to say once you get time you will have a lot to share!). So, don’t worry I’ve lot to share and have created a list of blogs to share with you.

Today, one of my colleague faced “No such host is known” error, and I faced it so earlier and found solution for it as well (What, you are also facing the same error? And searching for a solution? calm down, We’ve solution for you!). At that time he told you should post it. And it inspired me to write this blog post.

and it fixed our issue and same for my colleague too!

But today, did a quick search on forum and web and people have suggested different solutions. Which you can also try if above given solution doesn’t works for you:
