A brief guide to fix “Secure Connection Failed” Error in Firefox and Chrome
SSL connection error irritates end users and harms the website’s reputation.

Secure Connection Failed Error in Mozilla and Chrome Browser
The Secure Connection Failed error in Mozilla Firefox is shown in the below image.
In Chrome browser, the secure connection failed error looks like “This site can’t provide a secure connection”. The Chrome browser displays such errors if SSL protocols do not support the site.
Why does the “Secure Connection Failed” Error happen?
Secure Connection Failed error occurred due to a few reasons, which are as follows.
- Expired or invalid SSL certificate: Secure Connection Failed error can be caused due to expired SSL, invalid SSL certificate or the certificate is not installed correctly.
- Firewall prevention settings: If the firewall settings prohibit specific sites and limit the browser’s ability.
- Different Encryption Protocols: If the protocols of a browser and the website are different, it can create a conflict between the browser and the website. As a result, it can cause failed connection errors.
- Incorrect browser settings: If the browse settings are modified or not set by default, it may cause a failed error connection.
- Incompatible browser add-ons: Browser add-ons sometimes are not compatible with SSL connection and can interrupt between the secure connections.
- No SSL certificate is installed: It is necessary to install an SSL certificate on the server if it is not there as it can cause such an error.
- Force HTTPS not enabled: Force HTTPS that redirects all webpages to HTTPS instead of HTTP by default. It redirects users to a secure website connection. If it is not enabled, it can cause a secure Connection failed error.
- Outdated SSL cache: You should clear the SSL cache if not done, as it is a minor factor but still can cause an error.
- Incorrect Date and Time: System date and time always affect SSL connection, so it is better to synchronize them with the current time.
