Justanapplehelper,

Is your iPhone running the latest iOS 15.6.1? If not, let's use the steps below to get updated:

1. Back up your device using iCloud or your computer.

2. Plug your device into power and connect to the internet with Wi-Fi.

3. Go to Settings > General, then tap Software Update.

4. If you see two software update options available, choose the one that you want to install.

5. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don't know your passcode, learn what to do.

You can also find those steps in this resource: Update your iPhone, iPad, or iPod touch - Apple Support Updating can help address odd behaviors, and may help with renewing that particular certificate.

Should that still persist after updating, clearing the website data on your iPhone would also be a helpful troubleshooting step: If Safari isn't loading websites or quits on your iPhone, iPad, or iPod touch - Apple Support That process doesn't impact any other data or information on your iPhone, such as photos or videos.

1. Go to Settings > Safari.

2. Tap Clear History and Website Data.

3. Tap Clear History and Data to confirm.

Let us know your results, and we'll keep moving forward from there.

Hello Justanapplehelper,

We understand that you would like to remove an expired certificate from your device. We will be glad to assist. To manually remove an installed certificate, go to Settings > General > Device Management, select a profile, tap More Details, then tap the certificate to remove it.
