Hello haseeb210,
We see that you're having an issue opening websites after updating the software on your iPhone. We understand needed to be able to access websites from your device, and we'd be happy to help.
We were able to test this on our end and it appears that it could be an issue from the host side.
We suggest clearing your Safari history and testing again. This article will guide you through those steps, if needed.
Clear the history and cookies from Safari on your iPhone, iPad, or iPod touch
If the issue remains after clearing Safari history, you might want to reach out to the website's support or developer.
Thank you for using Apple Support Communities.
