why iphone saying server is not responding

Hi Elsiemarion,

Thanks for posting in Apple Support Communities.

We understand you're encountering an error message and your internet is slow. Is it your Wi-Fi, cellular, or both that are affected? Are you trying to access specific content or an app when this error occurs? Make sure iPhone is running the latest software in Settings > General > Software Update. Restart iPhone.

Feel free to provide more details to this post.

Regards.

Those 2 symptoms together are frequently associated with VPN connections. If you are using VPN stop; it isn’t needed on an iPhone, it offers no real protection (and actually increases the risk of personal data being compromised by the VPN vendor) and can cause many connection problems, as well as slowing down connections to about 25% of the available bandwidth.

If you are not using VPN further troubleshooting is needed, but if you are, don’t just turn it off, delete any VPN apps or VPN profiles and restart your phone.
