A user agent is a computer program representing a person, for example, a browser in a Web context.
Besides a browser, a user agent could be a bot scraping webpages, a download manager, or another app accessing the Web. Along with each request they make to the server, browsers include a self-identifying User-Agent HTTP header called a user agent (UA) string. This string often identifies the browser, its version number, and its host operating system.
Spam bots, download managers, and some browsers often send a fake UA string to announce themselves as a different client. This is known as user agent spoofing.
The user agent string can be accessed with JavaScript on the client side using the navigator.userAgent property.
A typical user agent string looks like this: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0".

We've had to do this because otherwise we get constantly overrun by inconsiderate or malfunctioning bots which overload the system. As such, we're forced to block traffic from popular web hosting companies, VPNs and Proxies, we also rate limit requests and have some other checks too.
Have you tried Microsoft Edge as the User Agent ? Try 'Other” at the bottom of the pop-up, enter the user agent string and “OK”.
In this post, I’ll discuss the HTTP user agent field and demonstrate how you can use Sorry to hunt for HTTP-based malware. Like many client-server protocols, HTTP requires that the client and server negotiate how content will be delivered prior to exchanging information.
Whenever you browse the internet, any server is able to identify your web browser and the host OS of your system. It encodes the browser version, operating system and other small features to the server.
Making statements based on opinion; back them up with references or personal experience. There are ways to develop your website to progressively enhance itself based on the availability of features rather than by targeting specific browsers.
Making statements based on opinion; back them up with references or personal experience. An user agent (UA) string is able to be used to detect what version of a specific browser is being used on a certain operating system.

Platform identifiers change based on the operating system being used, and version numbers also increment as time passes. Mapping UA string tokens to a more human-readable browser name for use in code is a common pattern on the web today.

For instance, if an user agent identifies itself as a Firefox running on Android, web servers will serve web pages specialized for mobile devices. As mentioned earlier above, changing user agent in Microsoft Edge is extremely easy.
