To address this issue, installing an SSL certificate for WordPress websites is recommended. In this article, we will explore the steps to diagnose and fix this error, including:
- Scanning for SSL errors
- Resolving outdated TLS protocols
- Fixing certificate name mismatches
- Troubleshooting software
By following these steps, users can browse securely without encountering this error.
Understanding the Error
What causes the ‘ERR_SSL_VERSION_OR_CIPHER_MISMATCH’ error in WordPress?
This error typically occurs when there is a mismatch between the SSL/TLS protocol versions supported by the server and the client.
It can also be caused by issues with SSL certificate verification or incorrect SSL certificate installation.
To troubleshoot this error, you can check the SSL certificate and protocol versions, scan your website for SSL errors, and fix any outdated TLS protocols or cipher suites.
Scanning Your Website for SSL Errors
To scan your website for SSL errors, use online tools such as Qualys SSL Labs SSL Server Test.
This tool provides a detailed report about the SSL certificate and allows you to check the supported versions of the TLS protocol in the configuration section.
If no SSL errors are found, the issue may be with the user’s computer.
Troubleshoot the software on the computer to fix the error.
Fixing Outdated TLS Protocols and Cipher Suite
To resolve the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error in WordPress, it is crucial to update the TLS protocols and switch to secure cipher suites. Outdated TLS protocols (such as TLS 1.0 and TLS 1.1) and insecure cipher suites (such as RC4) can pose security issues.
Contact your hosting provider to enable TLS 1.2 or TLS 1.3 and switch to AES-GCM cipher suites. Consider moving to reliable hosting providers like Bluehost or SiteGround, who do not use insecure versions of TLS or cipher suites.
Resolving SSL Certificate Name Mismatch
To resolve the SSL certificate name mismatch error in WordPress, there are several steps you can take:
- Verify that the domain name on the SSL certificate matches the website’s domain name.
- Update the SSL certificate to ensure it includes all variations of the domain name.
- Check the SSL configuration to ensure it is properly set up.
- Verify the domain setup to ensure it is correctly configured.
- Troubleshoot CDN issues to ensure SSL compatibility with the CDN.
Troubleshooting Software on the User’s Computer
Troubleshoot software conflicts on the user’s computer to resolve the ‘ERR_SSL_VERSION_OR_CIPHER_MISMATCH’ error in WordPress.
Start by updating the web browser to the latest version or switching to a modern browser like Google Chrome.
If unable to update the browser, enable a later version of TLS in the browser settings.
Additionally, check the antivirus software settings or temporarily disable it as it can also cause the error.
Clearing the browser cache, checking network settings, and updating the operating system can also help resolve this issue.
