If a user receives a "404 The request resource cannot be found" error after trying to access a newly created virtual proxy, what is likely the reason?

The reason for the "404 The request resource cannot be found" error when accessing a newly created virtual proxy often points to issues related to the configuration or the routing of requests within Qlik Sense.

When a user accesses a virtual proxy, they typically use a URL that includes a prefix for that proxy. If this prefix is incorrect or misconfigured, it will lead to the server being unable to locate the resource, thus resulting in a 404 error. This situation mirrors the concept of navigating to a webpage using a broken link or an invalid path, wherein the server cannot find the requested resource because it doesn't match any existing routes or configurations established on the server.

By addressing the prefix configuration in the virtual proxy settings, users can ensure proper routing and thus avoid encountering this error when trying to access the intended resources.

The other choices, while they indicate potential issues, do not directly address the specific nature of a "404" error related to routing and resource availability associated with the virtual proxy setup.
