There are a lot of SSL errors out there.
Way too much, right?

Quick fix

Did you receive the error message “ssl error no cypher overlap” while using Firefox or another web browser? Then you are dealing with one of the most common SSL errors. The cypher overlap error occurs due to a misconfiguration of the TLS/SSL settings.

The SSL error can easily be solved by adjusting the settings in your browser. If you are using Mozilla Firefox, access the settings page and choose the add-on section. Check the add-on list for any extensions that you did not install yourself. Deactivate all unnecessary add-ons and plug-ins, then restart the browser.

You can also reset both the TLS and the SSL settings. In your brower, type about:config to open the settings. Type TLS in the search box and look through the TLS settings. If there are any modified settings, restore them back to default. Repeat these steps to reset the SSL settings as well.

The common SSL error “ssl error rx record too long” may occur in your browser when visiting a website via HTTPS. The error is often accompanied by the error message “SSL received a record that exceeded the maximum permissible length” or a similar message. This means that the web server is sending HTTP data instead of HTTPS data.

This common SSL issue is usually caused by an error in the SSL implementation on the server itself. There are several things that you can do to solve the problem:

1. Ensure that SSL is configured correctly on the server.
2. Check if your browser is using the same port as the web server. To use port 443, some servers such as Apache require a configuration first.
3. If you are using a proxy server, the error can show up as well. In this case, make sure that your local proxy is configured correctly.

The error message “SSl certificate problem: unable to get local issuer certificate” sometimes occurs when making a request for a secure HTTPS destination. The SSL error is caused by a problem with the root certificate. When you use client SSL and make a request for a secure HTTPS source, you need to verify your identity by sharing your SSL/TLS certificate. If this step is not completed successfully, the error message pops up.

There are several solutions to fix the SSL certificate problem:

1. Change php.ini while maintaining SSL.
2. Maintain SSL and add the following code:

$ch = curl_init();

$certificate_location = ‘/usr/local/openssl-0.9.8/certs/cacert.pem’;

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, $certificate_location);

>curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, $certificate_location);

3. Disable SSL (not recommended).

Error code “ssl protocol error” is a typical SSL error on Google Chrome. Your browser may also state the error message “This site can’t provide a secure connection” along with the error code. If you encounter this problem, there are many possible solutions:

1. Set the correct date and time on your system, as the SSL certificate is sensitive to your system’s settings.
2. Clear your browser’s SSL state in the Google Chrome settings.
3. Disable QUIC protocol which is enabled by default in Google Chrome.
4. Check your antivirus settings and make sure it scans SSL/TLS protocols correctly.
5. If the website’s SSL/TLS protocols are not in line with your Chrome version, change the SSL/TLS protocol settings accordingly in the advanced settings.

Quick fix

The SSL handshake error message can be received when the SSL handshake process fails. The SSL handshake is a process in which the browser sends a secure connection request to the web server. If this request fails, it results in the SSL handshake failure alert.

The SSL error can be caused by a number of reasons. Therefore, the solution depends on the cause. These are the most common ones:

1. The SSL/TLS protocol is not supported by the server.
2. The certificate does not match the hostname in the URL.
3. The certificate is invalid or has expired.
4. The client server is unable to communicate with the servers.

You can fix the problem by adjusting the settings and by making sure that the SSL/TLS certificates are configured correctly.
