Google Chrome can be configured to save the browsing session on close so that the user can continue the session on the next startup. All websites and services that had been open in tabs are reopened on the next browser start. It sometimes happens that Google Chrome cannot open a website, displaying a dreaded "Oops! Google Chrome could not connect to" error instead.
Strange if the site was working fine some time ago. Users who check the website in another browser installed on the system may find out that the page loads and displays fine in that browser which leads to the only possible conclusion that it is a Google Chrome problem.
The majority of page loading problems are a result of the DNS Fetching in Google Chrome. DNS Pre-fetching stores information in the browser to speed up the loading of websites in Chrome. It can, under certain circumstances, result in connection problems. This can happen if a wrong or outdated DNS is stored in the browser for the website in question.
DNS Fetching speeds up page loading by about 250ms. Chrome users who experience connection difficulties regularly might want to try turning the feature off to see if it resolves the issues.
This is done in the Chrome options. A click on the Wrench icon in the upper right corner and the selection of Options opens the settings window of the web browser.
Load the Under the Bonnet tab and locate the entry Use DNS pre-feching to improve page load performance. Remove the checkmark from that setting to disable DNS fetching in the browser. The websites with connection issues should load fine immediately.
Update: Google has changed the name of the feature slightly. You need to perform the following actions in Chrome to resolve the issue. Click on the wrench icon in the Chrome status bar and select Settings from the context menu.
Click on Under the hood in the left sidebar menu, and locate Predict network actions to improve page load performance on the right side.
If that setting is enabled, disable it with a click in its box. the settings are automatically saved afterwards.
Update 2: Google has once again changed the menu structure of the browser. You now need to click on the settings icon (the three horizontal bars on the top right) and select settings from the context menu that opens. Here you then need to scroll down to show advanced settings.
Uncheck "Predict network actions to improve page load performance" here.
Update 2: Google has redesigned the Chrome browser. Here are the updated instructions to turn off the feature:
