Understanding Different Types of Browser Errors

Posted on January 28th, 2017

In this tutorial we can check different types of browser errors and what it means.

 

Certificate Error

Certificate error is an SSL certificate error or security certificate error. This type of errors occurred while connecting to a website using HTTPS. The browser displays these types of error when the browser cannot verify the real owner of the website using SSL certificate. Certificate error may occur whenever a website is using a self-signed certificate or shared SSL for their websites. When you see a certificate error in browser, this indicates that you are not connecting to the real website.

 

Server Not Found

This is a 404-error code. Server not found errors occur when you have a problem connecting to the website. This indicates that the browser could not find the website you are trying to access. Several reasons behind the server not found errors is when you are trying to visit website that doesn’t exist, DNS server is down, misconfigured firewall, proxy, or other settings, mistyping of website address etc… For more information, you can refer https://www.interserver.net/tips/kb/404-error-fix/

 

Unable to Connect

This type of errors is similar to server not found errors. This indicates that the browser has successfully contacted the DNS servers and identified the website, but the browser did not receive a response from the website’s servers when it tried to connect. If you are experiencing these types of errors, it means that the website itself is down or experiencing problems.

 

Service Temporarily Unavailable

This is a 503-error code and it means that the web server is currently not available. This is a temporary condition and will be resolved after some delay. This does not mean that the site is permanently unavailable. You can check the internet connection to resolve these types of errors.

 

Forbidden

This is a 403-error code. This error occurs when you do not have permission to view the website contents. The server administrator has protected the website content so that it cannot be available by to the public. If you are experiencing these types of error, you need to contact the server administrator to correct the permission of website contents.

Gateway Timeout

This is a 504-error code. This type of error occurs when a proxy server needed to communicate with a secondary web server, such as an apache server, and access to that secondary server timed out. It could be occurring when a DNS server is down, network issue, unable to process the request etc…

 

Internal Server Error

This is a 500-error code. It is the most well-known server error. The 5xx errors are the status codes returned by the server when the server encounters an unexpected condition which prevented it from fulfilling the request from a client. The 500 Internal Server Error is the general catch all error when the server throws an exception. It is the error message when no more specific error message is suitable.
