Can't login to Remote Test Lab

When I login to RTL and go to All devices page, it shows Sign Button and I can’t select any device with notification “Please sign in if you want to use the Remote Test Lab service.” If I click on the Sign in button, page is just reloaded. The error from browser console: GET https://developer.samsung.com/remotetestlab/rtl/api/v1/users/me 401 (Unauthorized) Tried from another remote PC, located at another country. The same result.
