OpenVPN is a popular open-source virtual private network (VPN) protocol that allows you to securely connect to the internet and protect your online privacy. Tunnelblick is a free and user-friendly OpenVPN client for macOS. However, sometimes you may encounter an error message saying "Unrouteable TLS received" when trying to connect to the Riseup VPN service using Tunnelblick. In this article, we will explore the possible causes of this error and provide solutions to help you resolve it.
What does "Unrouteable TLS received" mean?
The error message "Unrouteable TLS received" indicates that the OpenVPN client (Tunnelblick) received a Transport Layer Security (TLS) packet that it cannot route to the intended destination. This error commonly occurs when there is a mismatch between the server address or certificate and the client's configuration.
Possible causes of the error
There are several potential causes for the "Unrouteable TLS received" error:
- Incorrect server address: Ensure that you have entered the correct server address provided by Riseup VPN. A small typo in the address can cause this error.
- Expired or invalid certificate: If the server's TLS certificate has expired or is invalid, the client will reject it, resulting in the error message.
- Firewall or network configuration: Sometimes, firewall rules or network configuration settings can interfere with the VPN connection and cause the error.
- Outdated software: Using an outdated version of Tunnelblick or OpenVPN can lead to compatibility issues and trigger the error.
Resolving the "Unrouteable TLS received" error
Now let's explore some troubleshooting steps to help you resolve the "Unrouteable TLS received" error:
1. Verify the server address
Double-check the server address you have entered in Tunnelblick. Make sure there are no typos or missing characters. You can find the correct server address in the Riseup VPN documentation or by contacting their support team.
2. Update Tunnelblick and OpenVPN
Ensure that you are using the latest versions of Tunnelblick and OpenVPN. Outdated software may have compatibility issues that can cause the "Unrouteable TLS received" error. Visit the official websites of Tunnelblick and OpenVPN to download and install the latest versions.
3. Check the server's TLS certificate
If the server's TLS certificate is expired or invalid, you will need to obtain a valid certificate from Riseup VPN. Contact their support team for assistance and follow their instructions to install the new certificate.
4. Disable firewall temporarily
Temporarily disabling your firewall can help determine if it is causing the "Unrouteable TLS received" error. If the error disappears after disabling the firewall, you may need to adjust the firewall settings to allow the VPN connection. Consult your firewall's documentation or seek assistance from your network administrator to configure the firewall correctly.
5. Check network configuration
Ensure that your network configuration settings are not interfering with the VPN connection. Check if any proxy settings are enabled or if there are any specific network restrictions in place. Disable any proxies and ensure that your network settings allow VPN connections.
6. Reinstall Tunnelblick
If none of the above steps resolve the issue, you can try reinstalling Tunnelblick. First, completely remove the existing installation by dragging the Tunnelblick application to the Trash. Then, download the latest version from the official Tunnelblick website and install it again.
