Resetting network settings on an iPhone will remove any existing proxy configurations, which can potentially resolve issues with the proxy not working properly and causing a lack of internet connectivity. Here's how resetting network settings impacts proxy settings on an iPhone:
- All saved proxy settings, including the hostname, port, and authentication details, will be deleted[1][3][5]. This includes any manual HTTP proxy configurations entered in Settings > Wi-Fi > [Your Network] > Configure Proxy > Manual.
- Custom proxy settings for individual apps or the system will be reverted to the default "No Proxy" state[2][4]. This can help if a specific app's proxy configuration is causing problems.
- Any SSL certificates installed for proxy tools like Charles or OWASP ZAP that are not trusted will be removed[2]. This resolves potential certificate trust issues.
- Resetting network settings also clears other network-related settings like Wi-Fi passwords, VPN configurations, and cellular preferences[1][3][5]. This gives the iPhone a fresh start with its network settings.
After resetting network settings, you'll need to re-enter the proxy details if required and ensure the necessary SSL certificates are trusted again in Settings > General > About > Certificate Trust Settings[2]. This process can often fix issues with proxies not working and restoring internet access on the iPhone.
However, it's important to note that resetting network settings will also remove all saved Wi-Fi passwords and other network configurations, so it's recommended to have this information backed up before proceeding[1][3][5].
