Iphone proxy no internet connection

Common Issues

1. Proxy Configuration Not Taking Effect: Users have reported that after entering the proxy settings (hostname, port, authentication) in Settings > Wi-Fi > [Your Network] > Configure Proxy > Manual, the proxy does not seem to work. Apps may display a "no internet connection" message despite the settings appearing correct[1][2].

2. Apps Not Functioning: Even when the proxy is set up correctly, apps may fail to load or refresh data, indicating a lack of internet access. This has been observed with various applications, including Safari, which might show a warning about insecure connections[2][3].

3. Certificate Trust Issues: When using proxies like Charles or OWASP ZAP, if the necessary SSL certificates are not trusted on the iPhone, it can lead to connectivity issues. Users must ensure that any manually installed certificates are trusted in the device settings[3][4].

Solutions

1. Reset Network Settings: A common recommendation is to reset the network settings on the iPhone. This can be done by going to Settings > General > Reset > Reset Network Settings. After resetting, users should re-enter their Wi-Fi credentials and proxy settings[1].

2. Check Proxy Details: Ensure that the proxy server IP and port are correctly configured. Double-check these details, as incorrect information can lead to connectivity issues[4].

3. Disable VPNs: If a VPN is active on the iPhone, it may interfere with the proxy connection. Users should turn off any VPN applications and then try reconnecting to the proxy[4].

4. Trust SSL Certificates: For proxies that require SSL interception, make sure the certificates are installed and trusted on the iPhone. This can be done by going to Settings > General > About > Certificate Trust Settings and enabling trust for the installed certificates[3].

5. Reinstall Proxies: If issues persist, uninstalling and reinstalling proxy applications or certificates may help resolve underlying configuration problems[1].

By following these steps, users can often restore internet access on their iPhones when using a manual HTTP proxy.
