Mendix User Management API Not Working

Hello all, I am currently trying to use the User Management API to be able to deactivate/activate users. When testing this api using Postman I get a 503 response error back but it still deactivates the account. When reactivating the account it gives a 200 success code back, which is expected. Also, it takes 30 seconds for the api to run to deactivate a user. Any ideas on how I can get a 200 success code when deactivating a user and how to get the api to run quicker? I attached an image of my postman to show that I have everything setup correctly.

I think in the example they use method POST instead of PUT
