The first step you'll want to take is to check on Apple's service status page that iCloud Private Relay is down. If it is, you'll just have to wait for Apple to sort out the server issues on their end.

Can you not see the option for a Private Relay service in your settings? Make sure your iPhone is capable of running iOS 15 here and update, otherwise you won't be able to use the service. Also, you'll need an active iCloud+ subscription.

You may have Private Relay turned on, but it might not be running on your current data or WiFi connection. Don't worry, this can happen with any VPN, we just need to make sure it's synced up.

Go to Settings > Data or WiFi (depending on which connection you are currently using. Then, tap the ‘i' icon next to the current connection then turn on Private Relay by taping the toggle just there. Next, go to your home screen and swipe up to access the app drawer. Find your open mail app and close it. This should then resolve the ‘iOS your network settings prevent content from loading privately' issue.

Running a VPN service alongside Private Relay will just conflict with it and cause issues. Make sure to uninstall any other VPN services if you wish to use Private Relay. Also, your Firewall or Antivirus app may be blocking your mail app's connectivity, make sure to go into your Anti Virus, Malware, or Firewall software and make an exception or whitelist your chosen mail app.

There is a chance you may be seeing the “iOS your network settings prevent content from loading privately” error due to having Mail Privacy Protection turned on.

You can disable the ‘protect mail activity’ option but you'll also be risking privacy issues by doing so, so do this at your own risk. Go to Settings > Mail > Privacy Protection, then finally diable Mail privacy protection by toggling the switch to the off position.

Limit IP address tracking seeks to hide your IP address, so that email trackers don’t have access to it. That’s great, but it can mean seeing an error in the Apple Mail app.

To disable it:

1. Head to Settings > WiFi Settings
2. Select the ‘info’ icon next to your next to your network
3. Scroll down and when you get to the “Limit IP address tracking” toggle, toggle it off.

In the case where you’re actually no on WiFi and using cellular data…but still seeing this error, do the following:

1. Head to Settings > Mobile data and select ‘Mobile Data Options’
2. Turn off the ‘Limit IP Address Tracking’ option.

The “iOS your network settings prevent content from loading privately” error should now be resolved. I

If you are still having issues after these steps, there is one final, more dramatic, option. Before this though, make sure your iPhone is backed up. Make your you have backed up your data via iCloud or another cloud storage method before resetting:
