If you’ve been surfingg the internet for a while, you most likely ran into some common web broswer errors. Usually the errors are common issues with the browser, but sometimes they be malicious and have the ability to ruin your computer. Here are some the most common web browser errors:
An SSL or security certificate error is probably the most common web browser errors that we see. It pops up when you connect to a website that uses HTTPS. Usually the certificate error will alert you that there are some issues with the HTTPS encryption of the website. A website that is encrypted with HTTPS presents certificates that the browser uses to identify the legitimacy of the website, therefore preventing you from accessing and sharing vital information with a website that is counterfeit.
Unable to connect
This is another example of common web browser errors. This error message indicates that your web browser has successfully established a connection with its DNS servers but failed at receiving a response when trying to connect to the website’s servers. This error is typically caused when a website is undergoing maintenance or is simply not available. Any issues with your computer’s internet connection firewall or proxy can also prompt this error message.
Web forgery warnings
When accessing certain sites your browser will display warnings that are related to malware or phishing that are known as web forgery. These errors are displayed when you try to connect to any websites deemed dangerous by the web browser’s list. These dangerous websites are known to have malware and other malicious programs that can trick you into giving up confidential information that can lead to your identity being stolen.
Server Not Found
Another common type of browser-related issue is the “Server Not Found” error. This error indicates that the browser cannot find the website that you are trying to access. The “Server Not Found” error can pop up if you mistype the website address or if the website does not exist. This error can also be caused by a misconfigured firewall, proxy or network settings.
404 Not Found
You have likely come across the “404 Not Found” error while browsing the web. This indicates that the website you are trying to access does not exist. Either it is no longer available or perhaps you have typed in the wrong address.
Error 403: Forbidden
This error will pop up when you try to load a web page that you do not have permission to access. Typically, this error message means that you have entered a URL or clicked on a link that leads to a page that has been set up with access permissions. That means that you have to have an account to enter the web page.
Error 401: Authorization Required
The 401 error happens when you try to access a web page that requires a password. You must have the approved password in order to access the website.
Error 405: Method Not Allowed
This error is actually a less common error and you may have never seen it. But, in case you come across it, the 405 error means that the server understands what the common web browser errors is asking for, but it is refusing to complete the request. This can happen as a result of an error in the website’s code or a fault redirect.
Error 500: Internal Server Error
The 500 error is extremely common. When a server encounters a problem that prevents it from fulfilling a request and the problem can not be described by one of the other error codes, the server will generate a 500 error. If you see the 500 error, try reloading the web page, clearing the cache, deleting cookies and then restart the browser and try again.
Error 503: Service Unavailable
This error means that the web browser is not able to process your request. When you see this type of error, it could mean the server is undergoing maintenance or it could be overloaded with requests. The best option when you see a 503 error is to try accessing the web page again later.
