I’m having the same problems here. I already searched for everything and nothing is working here. I already changed the way I was doing. I already changed the http://localhost:5000/api/users for http://myLaptopIP:5000/api/users and still not get any result. I’ve tried using another apis and that worked perfectly, and also when I type it on the postman but using the localhost:5000/api/users, I get all the results. I don’t know what kind of issue I’m facing. Does someone know how to check if my firewall is blocking the access?

Thanks a lot guys!
