DNS lookup failure is a common problem in Google Chrome browser if you are using a broadband connection. This problem often occurs when your internet connection is not properly working or it could arise when the DNS server is no longer responding.

However, to fix the problem, you may have to try several things. Just follow the fixes given below in chronological order. Try the methods one after another.
Fix 1: Flush DNS
Windows and other operating systems store all their DNS data in the cache. The essence of this storage is to facilitate the connection. Your DNS provider is always queried any time a connection attempt is made, especially when the information needed was not available. The DNS cache also has a privacy implication. The cache contains information from websites you have visited before. When you flush the cache, you remove all the entries contained in it. Flushing the DNS cache is not difficult. It can be flushed through the commands line.
The simplest way you can do this is by pressing Windows Key + R, and then type cmd, and hit the enter button. A black window will popup. Write ipconfig /flushdns in that window and press enter.
This ensures that all the records in the DNS cache have been removed which could solve chrome connection problem.
Fix 2: Change DNS Server Addresses
