Safari on my iPhone is messed up. What can I do?

Most recently used list

Open the App Switcher

• On an iPhone with Face ID: Swipe up from the bottom edge and pause in the center of the screen.
• On an iPhone with a Home button: Double-click the Home button.

Restart the iPhone, and try again.

If you have an add-on VPN client app, or an add-on security app, remove it and try again.

If you’re on a home Wi-Fi network, restart your router and try again.

Switch off Wi-Fi and use cellular data, and try connecting to the website.

So to confirm, you can connect to the website via cellular, but cannot via Wi-Fi?

Try the phone on a different Wi-Fi.

If both cellular and a different Wi-Fi work, then start looking at your Wi-Fi.\ as the problem.

In what way is it messed up?

Delete Safari from most recently used list, reboot iPhone and try again (check the URL)
