Netgear OpenVPN TLS Key Negotiation Failed – How to Fix
Whenever I try to connect to my router’s OpenVPN, I get the “TLS handshake failed” error message – said a Netgear router user. FYI, the user gets the Netgear OpenVPN TLS key negotiation failed error message when the router is unable to authenticate the OpenVPN certificate. This certificate originally belonged to your OpenVPN client. Why does the error show up and how to get rid of it? Let’s find out.
Reason: Netgear OpenVPN TLS Key Negotiation Failed
The TLS handshake error message can show up when the certificate version is older or multiple users are using the same certificate to connect to the WiFi router’s OpenVPN.
To fix this error, you are supposed to add a remote-cert-tls server to the OpenVPN file that is generated through the WiFi router. Changing this file facilitates the server to check the certificate again while attempting a connection with the Netgear router’s OpenVPN server. Apart from doing that, you are suggested to ensure that the browser in use matches the requirement to connect to the OpenVPN server. Here’s how the web browser is supposed to be:
- Updated to the latest software version
- Free of cache
Moving ahead, let’s find out how to resolve the TLS handshake error message by adding the remote-cert-tls server to the OpenVPN file.
Fixed: Netgear OpenVPN TLS Key Negotiation Failed
You will need the default password (password) and username (admin) of the router to get into its Settings panel and add the server. However, you can use the customized details if you have changed them during the router setup process. Besides, if you get the routerlogin.net not working error while executing the process, consider accessing the router’s default IP. Although a majority of Netgear routers support the use of the 192.168.1.1 IP address, you should use the product’s user manual to know the correct IP address.
Follow the steps given below to resolve the “TLS handshake failed” error message:
- Load an internet browser on a computer or mobile phone that is connected to the Netgear router’s network.
- After that, visit routerlogin.net or access the default router IP address.
- The login window of the router will show up.
- Here, you are supposed to input the router’s login details.
- Hitting the Log In button will open up the Status page of the router.
- Click ADVANCED.
- Choose the OPEN VPN option to navigate to its service page.
- Select the check box adjacent to the Open VPN Service if not selected.
- Now, move to the OpenVPN configuration packet download section.
- Click the FOR SMARTPHONE button and download the router’s VPN configuration files to your client devices (Android, iOS device, or computer).
Note: In case you download the file on the computer, you will be required to unzip the files first and send them over to the Android or iOS devices. The file includes the .ovpn file.
- Once done, you need to launch the OPENVPN CONNECT app.
- Import the .ovpn file.
- Select the OpenVPN client on the dashboard.
- Choose EDIT CONFIG to open a text editor.
- Add the line remote-cert-tls-server to the file and click Save.
This is how you can get rid of the Netgear TLS handshake failed error. You are now free to connect to the Netgear router OpenVPN.
In a Nutshell
Our guide to fixing the Netgear OpenVPN TLS key negotiation failed error message ends here. In this post, you got to learn that the error is likely to appear when the OpenVPN certificate is running on the older version. The only hack to correct this error is to add a remote-cert-tls server to the OpenVPN file that is generated through the WiFi router.
Apart from taking care of the points discussed in this post, you need to ensure that your computer is not connected to a network other than your Netgear router. The cable connections related to your WiFi router should be made with the help of an intact cable and must be finger-tight. Lastly, do not forget to power cycle the router after adding the TLS server. Doing so will fix the technical glitches and you will be able to connect to the Netgear router OpenVPN easily.
