How to Fix SSL Handshake Failed Error Code 525 (2024)

Are you facing the SSL Handshake failed error code 525? if your answer is YES then you are not alone.

SSL certificates are essential for connecting the user’s browser with the website server.

SSL allows users to make a secure connection between the web browser and the website they are trying to access.

If the website is SSL-certified you will see the HTTPS before the URL.

If you see the HTTP before the website URL it means the connection is not secure and as a result web browser shows a warning for accessing the website.

One of the common errors is SSL Handshake failure. This error appears when the web browser is unable to make a connection with the website server.

If you are wondering how to fix the SSL Handshake failed error code 525, you are in the right place.

In this guide, you’ll learn what causes the SSL Handshake failed error code 525 and how to fix it.

What Causes the SSL Handshake Failed Error Code 525?

You will receive the SSL Handshake failed error when the connection between the website server and web browser is not successful.

Anytime a web browser sends a request to make a secure connection, the server sends a public key with the certificate to the device from which it received the request after automatically checking against the list of CAs.

Once the web browser receives the certificate it will immediately generate the key and secure it using the public key received from the server.

The SSL Handshake failed error code 525 occurred when this handshake failed and the process was not successful.

This indicates the connection between a web browser and the server is not secure.

This will happen for several reasons, some of the most common reasons include:

  • Incomplete certificate chain.
  • Unsupported SSL/TLS protocol request from the server.
  • The hostname in the URL and the name on the certificate do not match.
  • The certificate is expired or invalid.
  • Unsupported cipher suite request from the server.
  • The server is unable to communicate and connect with the servers.

However, if you are getting the SSL Handshake failed error code 525, you can fix it using the methods below.

So without any further ado let’s get started:

How to Fix the SSL Handshake Failed Error Code 525?

Update Your Device’s Date and Time

Sometimes simply updating your device date and time will fix your problem.

So to start fixing the SSL Handshake failed error code 525 the first thing you can do is update your device date and time and check if the error is fixed or not.

Check whether your SSL certificate is active

As I mentioned earlier, this error may be the result of an expired or invalid certificate.

The SSL certificates will be expired after some time. If updating your device date and time does not fix the error, you should check the expiry of the certificate and make sure the SSL certificate is valid and active.

The SSl certificates come with an expiry date and are valid for a few months or 2 years.

Once the certificate exceeds the expiry date it will become invalid and as a result, your web browser will show you the error code.

Update your browser to use the latest SSL protocol

The SSL protocols are continuously changing and your web browser needs to support these protocols to access the website.

Sometimes users are encountering the issue because their web browser does not support the latest protocol.

This is happening because of the outdated version of the web browser or other technical issues.

In that case, you should update your web browser so that it will support the latest protocol.

If updating the browser does not fix this error, you should consider using another web browser.

Cipher suite mismatch

A cipher suit is a set of instructions that will secure the SSL network connection by helping the browsers connect with the web server securely.

If the web browser is unable to connect with the web server that uses an SSL certificate then the Cipher suit mismatch occurs.

This mismatch is one of the main reasons for encountering the SSL Handshake failed error code 525.

In that case, you should check the cipher suite mismatch using the Server Test Tool and replace them if you see the “WEAK” label for certain ciphers.

That’s all you need to know about how to fix the SSL Handshake failed error code 525.
