[Fixed]: Server Error in ‘/’ Application. Runtime Error in SharePoint

In SharePoint, sometimes, we may get this error “Server Error in ‘/’ Application. Runtime Error”. When we try to access any of the SharePoint sites, including the central administration site, we will get the below error description:

Server Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".


<!-- Web.Config Configuration File -->

<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>

Solution

For the above error, the reason could be many. One of the vital reasons is SharePoint server lost connection to the SQL database server due to the network issue, so we need to focus on to the test the network connectivity from all SharePoint servers (APP, WFE) to the Database servers. If your network connectivity is fine or your database server cluster services are running fine, then we will not face this issue.
