iTunes can t verify the server, it shows that the certificate for this server is invalid, what shoul

There are these possible scenarios for an invalid server certificate:

1.The computer date and time are incorrect. Adjust the computer system time;

2.The server certificate is not trusted. If you are not trusted, you need to find a CA to re-apply for a server certificate, and you need to find GDCA to apply for a globally trusted certificate.

3.Problems with browser settings. Adjust browser settings:

Tools - "Internet Options" - Custom Security Level", turn the security level down, or click "Advanced", uncheck the "Warn about certificate address mismatch" and "Check whether the certificate is revoked" and other options, and try again.

The situation that the computer cannot run iTunes is inquired because of the Storm Audio-Visual Device installed on the computer. Since iTunes requires QuickTime to run, and the Qt plug-in of QuickTime will conflict with the Qt plug-in of Storm Video, if Storm Video is installed on the computer, iTunes will be installed successfully, but an error will occur when opening it. Another situation is that the old version of Storm Video has been installed before, and it can be used normally after installing iTunes, but after a period of time, iTunes will appear an error prompt, which is caused by the user upgrading Storm Video.

At this time, uninstall iTunes and Storm Audio, and then install iTunes first, and then install Storm Video software, because Storm Video checks that the computer has a Qt plug-in when installing, and it will not install its own Qt plug-in, so that there will be no conflict, and you can use iTunes normally.

The specific solutions are as follows:

1. Open the iTunes software and press the button to enter the preferences.

2. Open the "Parental Controls" option, check the iTunes Store and iTunes U under the Disable, and press the OK button.

3. Then close the iTunes software and reopen it, remove the iTunes Store and iTunes U that you have checked, and click OK again.

4. Reopen the iTunes software or access it directly to see if it can be accessed normally.

5. If you still can't use it, you can do it a few more times, if it really doesn't work, restart the computer, or uninstall the iTunes software on the computer and reinstall it.

Solution 1: Manually trust the certificate

Note: The principle of this method is to believe that the operator hijacked the ** certificate, so you may face the risk of being hacked and stealing private data after hijacking. Take macOS Sierra as an example.

Open the Safari browser, enter the address bar must add English character dots), and visit.

3.Trust the certificate.

4.When the visit is over, you can exit the browser. Restart iTunes, you will find that you have successfully contacted the Apple server (for example, my iTunes prompts that you can update to iOS). Successfully get in touch with Applef servers.

A lot of the time the above methods don't work.

Set the system time to normal time.

That's how I solved it.
