Troubleshooting suggestions

As this message suggests, there are a number of possible reasons for the problem.

Your connection is blocked by your ISP or government

If you live in a restrictive country then your connection may be blocked by your government. To bypass this, you can try using our alternative routing feature.

There is a problem with your WiFi connection

Try getting closer to your router. If that fails, try resetting your router (turn it off, wait at least 10 seconds, then turn it on again). Restarting your Mac can also fix many connection problems. 

Use the Tor network

If access to the Proton VPN website is blocked by your ISP or government, you can try using Tor to reach it. From here, you can download OpenVPN TCP configuration files that may help overcome the block (see below).

There is a problem with your internet service provider (ISP)

This may be due to maintenance being performed in your area, poor reception (if using a  mobile connection), a technical problem, or a problem with your account. You can identify if the problem lies with your ISP by connecting over a different network (for example, using your phone as a mobile hotspot rather than WiFi).

If the issue lies with your ISP, you can wait to see if it resolves itself (maintenance is completed, the technical issue is fixed, etc.) or you can contact your ISP. 

Your antivirus software is interfering with the VPN connection

If running antivirus software on your Mac, it may incorrectly interpret the connection to our VPN server as suspicious. Temporarily disable or remove your virus software to help identify the problem. 

If the connection works when your antivirus software is removed or disabled, try adjusting its settings or adding an exclusion for the Proton VPN app.

A proxy or firewall is interfering with the VPN connection

To disable system-wide proxy settings in macOS, go to SettingsNetwork → [your network] Details Proxies and ensure no proxy protocols are enabled.

Either Proton itself or the Proton VPN server you are trying to connect to is down

This may be due to routine server maintenance or a technical fault. You can check the status of Proton here, and the status of our server network here. If it’s an issue with an individual server, just connect to a server that is operational. 

Proton VPN keychain issue

If you enter the wrong login details several times, you might encounter an error message. If this appears, please verify that you are using the correct Proton username and password. If you do not yet have an account, you can sign up for a Free plan for macOS.

The Network Extension Agent, also known as neagent, enables your Mac to receive VPN authentication data from the keychain system. To allow your Mac to establish a VPN connection, you will need to enter your system password. Select Allow or Always Allow to continue.

To resolve a persistent keychain error, log out of your Mac user account and log back in, or restart your Mac.

Advanced troubleshooting

You can learn additional information about the problem by opening Terminal from the Other folder in Launchpad or the Utilities folder in your Applications folder.

1. Ping Proton VPN using the following command:


2. Run a traceroute using:


If neither command gets a response, there may be something wrong with your device or network. Please contact our support team with this data, along with your device and ISP information.

Try manually configuring OpenVPN using Tunnelblick

Our macOS app supports the OpenVPN, WireGuard, Stealth, and IKEv2 VPN protocols, and our Smart Protocol feature will automatically switch between different VPN protocols to find one that works.

However, to change VPN protocols, you must first sign in to the app. If the connection fails at the sign-in page, you can manually configure an OpenVPN connection to our servers using the open-source Tunnelblick app or a WireGuard connection using our WireGuard configuration files.
