Summary:
When trying to open Web TimeSheet in Chrome it shows up with this error message DNS Error – cannot find server.  Even if you click F5 to refresh the page the error persists. Closing and re-opening the browser and trying again does not help.
When you try using an alternate browser, like Firefox or Internet Explorer, the website loads up without any problem.

Cause:
The issue is Google Chrome specific, and has nothing to do with DNS Servers or users Internet connection. The support page on the Chrome website suggests that you clear your browser cache, delete the cookies and scan your computer for malicious software to fix the issue. Well, that may not fix your problem because the issue is not malware but a built-in Chrome setting that's possibly preventing certain websites from opening up in Chrome.
When you visit a webpage (like a search results page), Google Chrome will pre-fetch the IP addresses of all websites that are listed on that page. Since the browser has the IP addresses of all the links in advance, DNS pre-fetching ensures that any links that may you click on that webpage will load faster. However, when pre-fetching fails, something that’s not very uncommon, you may get the link broken error.

Resolution:

  • Open Google Chrome.
  • Click on Tools, then select Options (or Preferences on a Mac) under Hood and uncheck the setting that says Use DNS pre-fetching to improve page load performance.
  • This might increase the loading time of certain pages by a few microseconds but the misleading error message would not show up.
