How to Fix the SSL Error “No Required SSL Certificate Was Sent”

If you’ve encountered the frustrating SSL error message “no required ssl certificate was sent” while trying to access a website, don’t worry – you’re not alone. This common SSL/TLS error can prevent you from securely connecting to sites and disrupt your browsing experience.

In this in-depth guide, we’ll explain what causes this SSL certificate error and provide step-by-step solutions to resolve it, so you can get back to safely browsing the web.

Understanding the “No Required SSL Certificate Was Sent” Error

Before we dive into fixes, let’s discuss what SSL is and why this error occurs. SSL, which stands for Secure Sockets Layer, is a security protocol that encrypts data sent between a web browser and server.

Its successor, TLS (Transport Layer Security), is more commonly used today. Both SSL and TLS certificates enable secure, encrypted HTTPS connections.

The “no required ssl certificate was sent” error message indicates that the website’s server did not provide the necessary SSL/TLS certificate to establish a secure connection.

Without a valid certificate, your browser cannot verify the website’s identity and will block access to protect you from potential security threats.

Several factors can trigger this “no required ssl certificate was sent” SSL error, including:

• Misconfigured or expired SSL/TLS certificates on the website’s server
• Incorrect SSL/TLS settings in the server’s configuration files
• Issues with intermediate or root certificates in the certificate chain
• Outdated or corrupted browser cache and cookies
• Antivirus, firewall, or VPN software interfering with secure connections

Step-by-Step Guide to Resolving the SSL Error

Now that you understand the cause behind the “no required ssl certificate was sent” error, let’s explore various methods to resolve it.

Follow these steps in order until the issue is fixed:

1. Refresh the Web Page

Sometimes, a simple page refresh can resolve temporary SSL/TLS hiccups:

1. Click the refresh button in your browser or press F5 (Windows) or CMD + R (Mac).
2. If a normal refresh doesn’t work, try a hard refresh to clear the browser cache:

• Windows: CTRL + F5
• Mac: CMD + SHIFT + R

2. Check the Website’s SSL/TLS Certificate

If refreshing doesn’t help, investigate the website’s SSL/TLS certificate:

1. Click the padlock icon in the browser’s address bar.
2. Select “Certificate” or “More Information” to view certificate details.
3. Verify the certificate’s validity dates and issuer information.
4. Contact the website owner if you spot any issues or the certificate appears invalid.

3. Clear Browser Cache and Cookies

Corrupted browser data may interfere with SSL/TLS connections, so clear your cache and cookies:

Browser	Windows	Mac
Chrome	CTRL + SHIFT + DELETE	CMD + SHIFT + DELETE
Firefox	CTRL + SHIFT + DELETE	CMD + SHIFT + DELETE
Edge	CTRL + SHIFT + DELETE	CMD + SHIFT + DELETE
Safari	CTRL + ALT + E	CMD + ALT + E

1. Select a time range (e.g., “All time”) to clear data.
2. Check the boxes for cache and cookies.
3. Click “Clear Data” or “Clear Now” to delete.
4. Restart your browser and retry accessing the website.

4. Disable Browser Extensions

Browser extensions, such as ad blockers or privacy tools, may conflict with SSL/TLS certificates:

1. Open your browser’s extensions or add-ons manager.
2. Disable suspicious extensions one by one.
3. Reload the website after each disable to isolate the problematic extension.
4. Remove the offending extension or keep it disabled when accessing the site.

5. Update Your Browser

Outdated browsers might not support the latest SSL/TLS protocols, leading to the “no required ssl certificate was sent” error:

1. Open your browser’s “About” or “Help” page to check for updates.
2. If an update is available, download and install it.
3. Restart your browser and attempt to access the website again.

6. Temporarily Disable Antivirus, Firewall, or VPN Software

Security software can sometimes interfere with SSL/TLS connections:

1. Disable your antivirus, firewall, or VPN temporarily.
2. Retry accessing the website.
3. If successful, add the website to your security software’s whitelist or exclusions.
4. Re-enable your security software for protection.

Note: Only disable security software briefly for troubleshooting and always re-enable it afterward.

7. Check Your Computer’s Date and Time Settings

Incorrect system date and time can cause SSL/TLS errors:

1. Open your computer’s date and time settings.
2. Ensure the date, time, and time zone are accurate.
3. Enable automatic time synchronization if available.
4. Restart your browser and revisit the website.

Contacting Website Owners or Administrators

If none of the above solutions resolve the “no required ssl certificate was sent” error, the issue likely lies with the website’s server configuration. In this case:

1. Contact the website’s owner or administrator through alternative channels (e.g., email, social media, or contact forms).
2. Inform them about the SSL error and provide details, such as the browser, operating system, and any error codes.
3. Request that they investigate and resolve the SSL/TLS misconfiguration on their end.
