Could not load user profile

When we implement SharePoint or when we set up everything right from the scratch i.e. creating service application, web applications, site collections, host headers etc. at that time it might be a possible we did some mistake then it will come in the picture when we provide the site for testing to end users or testing team.

When an end user tries to access their personal My Site, he might encounter this error message.

This error occurs when the SP admin does not connect a User Profile service application with the Web application that hosts My Sites, or disconnects a User Profile service application from the Web application that hosts My Sites.

To resolve this error, please refer the following steps and your issue will be resolved:

1-In Central Administration-Click Application Management.

2-In the Web Applications section, click Manage web applications.

3-On the Web Application Management page, click the Web Application that hosts My Sites, and then, in the Manage section of the ribbon, click Service Connections.

4-In the Configure Service Connections Associations dialog box, ensure that a User Profile service application is selected and set as the default.
