Network Error POSIX 61 can suddenly stop your Mac, iPhone, or iPad from connecting to apps or services. This error usually shows as “Cannot Get Mail” and happens when your device cannot reach a server. It can be caused by network settings, firewalls, VPNs, or outdated software.
The good news is that with the right steps, you can fix it quickly and get your connection working again!
How to Fix Network Error POSIX 61?
1. Verify Server Availability
Ensure that the server you are attempting to connect to is up and running. A common cause of this error is trying to connect to a server that is not operational.
- Check if the server is powered on and accessible.
- Use tools like ping or telnet to test the server’s responsiveness.
- Confirm that the server is not experiencing downtime or maintenance.
2. Check Firewall and Security Settings
Firewalls can block incoming connections, leading to a “Connection refused” error.
- Review your firewall settings to ensure they allow connections on the required ports.
- Temporarily disable the firewall to test if it is the source of the issue.
- If disabling the firewall resolves the problem, adjust its settings to allow the necessary connections.
3. Inspect VPN Configurations
VPNs can sometimes interfere with network connections, causing errors like POSIX 61.
- Disconnect from any active VPNs.
- Attempt to establish the connection again.
- If the connection succeeds without the VPN, consider adjusting the VPN settings or contacting your VPN provider for assistance.
Disabling the VPN also helps fix the POSIX 96 error on iPhone.
4. Reboot Devices and Network Equipment
A simple reboot can resolve many network-related issues.
- Restart your computer or device.
- Reboot your router or modem.
- After restarting, try connecting again to see if the issue persists.
5. Update Software
On Apple devices, network drivers are included within system updates, so keeping your operating system up to date ensures your drivers are current. Outdated system software can cause connection issues, including POSIX 61.

- While Apple updates cover internal network drivers, external devices like routers or Wi-Fi adapters may require firmware updates from their manufacturer.
This also helps fix cellular network-related issues on iPhone.
6. Test with a Different Network
Sometimes, the issue may be related to your current network environment.
- Connect to a different Wi-Fi network or use a mobile hotspot.
- Attempt to establish the connection on the new network.
