Getting 404 Not Found On Every API

Hello everyone on community,

The problem I’m having is that when I try to trigger any API in my collection, doesn’t matter if it’s new or old, giving me the “404 Not Found” error as like this:

Everything was normal like a week ago, didn’t change any settings but this problem occurred.
I’ve checked my environments settings they are as should they be. What is causing the problem?
I appreciate any help. Thanks everyone.

That HTML error is specific to the API you are using.

Its hitting the server, but can’t find the resource.

I can only advise on checking the console logs and ensuring that the authentication, parameters\body was sent in the request as expected. That any variables are transposed correctly.
