Hi! I’m Grace Wilson, here to help you with your PIA S5 Control app login issue on your iPhone and the IP problems on your PC. To get started, could you please clarify a bit more?

1. When you try to log in on the iPhone app, do you receive any error message?
2. Regarding the IPs on your PC, are you unable to connect to specific IP addresses, or are you having issues with the proxy or VPN setup?

This will help me guide you more precisely through troubleshooting. Meanwhile, here’s a basic checklist we can start with:

### For iPhone login issue:
- Make sure your internet connection is stable.
- Restart the PIA S5 Control app completely (swipe it away from the app switcher) and try logging in again.
- If that doesn’t work, try deleting the app and reinstalling the latest version from the App Store. Many users have resolved login issues this way.
- Also, double-check your login credentials (username and password) are correctly entered.

### For PC IP address usage issue:
- Confirm that your PC’s network settings are correctly set and not blocking the PIA S5 Proxy connections.
- Restart your PC to refresh the network configurations.
- If you are using a proxy or VPN, try disconnecting and reconnecting to ensure proper assignment of IP addresses.
- Check firewall or antivirus settings to make sure they aren’t blocking PIA-related traffic.

Once you try these, please let me know what happens or if you see any specific messages. We can then proceed to more advanced troubleshooting if needed.

Are you satisfied with this starting point, or is there any specific detail you can add?
