What does error code 100 mean? 

Error code 100 is an error code that means the browser could not establish a connection to the server. It can be caused by a number of reasons, so the first thing you should do is check your internet connection. Other reasons include:

Bad response from server – The server might be down or overloaded and cannot handle all of the requests it is receiving at the time hence giving you a bad response.  Unsupported browser – You may also get this error if you are using an unsupported browser. In order to resolve this issue, you will need to upgrade your browser or use another one altogether. Corrupted files – If you’ve just downloaded some new software, then it’s possible that one or more files within that program have become corrupted during download or installation.

In some rare cases, it could also be because there’s a problem with the website’s security certificate. If this is the case, don’t hesitate to check our expert article on recommended fixes.

What are the most common browser not supported errors? 

A browser not supported error is an alert that web pages may display to users when their browser is incompatible with a particular website’s requirements. It can manifest in different forms, such as:

Error 400 Bad Request – This error occurs when the request sent by the client is invalid or malformed. The server returns this error when receiving a request with an empty body, partial content, or certain characters. Error 404 Not Found – This error occurs when a URL requested by the client does not exist on the server side and cannot be found by the server. It can sometimes happen because of incorrect linking or missing files on your web server. Error 500 Internal Server Error – This typically means that your web server has been unable to process a request because of an internal error or misconfiguration.

You can easily solve most browser errors by updating your browser or clearing cookies. In some cases, you may also not have enough memory for your browser to handle such requests, or a virus has infected your system. It is why we recommend that you install a reliable antivirus to prevent such occurrences.
