I got the same thing, requests running in the browser but not using the postman.
Since the mail carrier synchronizes all devices, it stores a lot of cache information that I consider. I clicked on my profile in the application and left all devices. Then I launched the application, did not log in, I clicked the βcontinue without signingβ button, which is a link located closer to the bottom of the login page. Then I was able to fulfill requests through the postman.
Then I signed a contract and everything was in order through the postman.
Note. I always had the SSL certificate verification Off in the request setup.
