The “No data received” or the ERR_EMPTY_RESPONSE error can often come while browsing websites on the internet. It simply means, that the website you’re trying to access isn’t responding or sending any data to your requests. Many of the users have faced this issue on their websites that use WordPress as a content management system but sometimes accessing other websites like YouTube and Facebook has also given this error. This error can technically come up on any site and 99% of the times, it is due to conflicts, corruptions on the website or the webserver, for example “Plugins conflicts on WordPress” or due to server or host cache such as memcache or apc cache. There is nothing much a user can do unless the site opens fine on other computers and not just yours.

Method 4: Hosting Provider
If this site is yours, speak to your hosting provider to see if they can restore site from a back up. Tell them if you’ve recently changed anything. The issue can also occur if there have been updates on the server-side such as the “WordPress Updating Automatically” or any of the plugins being updated or if the server has updated PHP or SQL (etc) on server level affecting all sites.
