SSL Handshake Failed Error Code 525
Installing a Secure Sockets Layer (SSL) Certificate is on using a WordPress site, which enables it to use HTTPs to ensure secure connections. Users can do a variety of things wrong in confirming a valid SSL certificate and making a great connection between the site's server and a visitor's browser. Users have encountered an SSL Handshake Failed error message and are confused about what this means when they are not alone. Also, this is a common error that many users own. This can be a very frustrating experience, but the good news is that you can take straightforward steps to resolve the issue.
How To Fix SSL Handshake Failed Error Code?
Start off by updating your system’s date/time
The user is likely not the main cause when this is an easy fix that will occasionally cause an SSL Handshake to fail.
Make sure your SSL certificate is within the date
The certificates will expire after several months to two years. Also, there are many SSL Certificate Checkers which will be available online. You can check to see the expiration date of the SSL Certificate. The user will be free and check the "Revocation status."
Update your browser to the current SSL protocol support
Users can switch to a different browser which can serve as the test here. Also, SSL handshake works, while the browser using isn't updated correctly. There is a protocol mismatch. This needs to be corrected on the browser. When the user opens the proxy settings, you can click Advanced. You have to make sure TLS 1.2 is checked and also make sure that the boxes for SSL2.0 and SSL 3.0 are unchecked.
Make sure your server supports SNI
The server name indication allows a server to host multiple TLS certificates on the same IP address. The SNI isn't enabled, and multiple TLS certificates are hosted on the server. The user will get a handshake failure because the server isn't told which certificate will be connected.
Your error may be due to a cipher suite mismatch.
Cipher suites are algorithms that will secure SSL/TLS network connections. The server uses cipher suites which Cloudflare doesn't support, this will cause a handshake error. The user can use the same Server Test Tool from above to check on cipher suite mismatch.
SSL Handshake Wiki
Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are two important protocols used to authenticate data transfers between servers and external systems which as browsers. SSL certificates are needed in order to secure the website using HTTP. The user doesn't get too in-depth about the difference between TLS and SSL. The main terms are often used interchangeably. The SSL handshake is the first step in the process of establishing an HTTPs connection. You have to authenticate and establish the connection when the user's browser and the website's server must go through a series of checks which is to establish the HTTPs connection parameters.
HTTP is an application layer protocol in the internet protocol suite model . This model is for distributed, collaborative, hypermedia information systems. This is the foundation of data communication for the World Wide Web, where hypertext documents include hyperlinks to other resources the user can easily access. The header fields of HTTPs are A-IM, Accept, Accept-Charset, Accept-Datetime, Accept-Encoding, Accept-Language, Access-Control, Request-Method, Access-Control-Request-Headers, Authorization, Cache-Control, Connection, Content-Encoding, Content-Length, Content-MD5, Content-Type, Cookie, Date, Expect, Forwarded, From, Host, HTTP2-Settings, If-Match.
