Configure crawler in SSL certificate warnings in SharePoint 2013

In SharePoint site, when crawler requests the connection to crawl a site, system will automatically generates the warning message if there is a problem with the SSL certificate. We can get the problem in SSL certificates whenever certificate is expired or it not signed by a trusted authority or certificate name is not same as site name.

If we are crawling only internal sites, we may get the SSL warnings in some cases like site names and certificate names are mismatched when the Administrator changed the server name or site name or organization using same certificate for multiple sites. For those cases it will be good to change the default crawler behavior to ignore the SSL certificate warnings.

We have to use the following procedure to specify the crawler to crawl the sites in SSL warnings. It will apply to all the content sources of the search service applications in the farm. We need to re crawl the sites that affect the search index. We must have the farm admin credentials for SSL certificate crawl. To configure the crawler for SSL certificate warnings

Click on the General Application settings in the Central Administration left side menu.

Click on Farm Search Administration Link in General Application settings page Search section.

We will be redirected into Farm Search Administration page. (We will navigate this page by clicking on the Search Service Application Page -> In the Search Service Application page Click on the Farm Administration link.) In the Farm Search Administration page, Farm-Level Search Settings section, click on the value of Ignore SSL warnings settings For Yes or No. Default will be NO.

In Search SSL Settings dialog box, If we don't want the crawler to crawl the site in the SSL certificate warning make Ignore SSL Certificate name warnings check box to be unchecked. Else we want the crawler to crawl the site if there is SSL certificate warning need to check Ignore SSL certificate name warnings check box checked. And click on OK.
