Security update shows as paused

Hi dympna162,

Thank you for this additional detail.

First, let's check if there is an update that is already downloaded on your device.

If yes, please erase that update then download it again.

1. "Go to Settings > General > [Device name] Storage.
2. Find the update in the list of apps.
3. Tap the update, then tap Delete Update.
4. Go to Settings > General > Software Update and download the latest update."

If that is not the case, please try a different known-good Wi-Fi network.

Based on the screenshot you've provided, the issue you are experiencing is likely network related.
