Private application using password flow suddenly stopped working in April

We have an application that regularly pulls call log information using the API, The app is set as Private and is in production.

Our application had been running correctly from November until April using the password flow and suddenly it stopped working. When I try to use any REST client to send the oAuth request I get back "Unsupported grant type", which I believe is different than "Unauthorized for this grant type".

The body that we send looks like "username={Username}&password={Password}&grant_type=password" just for example purposes.

Any idea why this is happening?

The HTTP body implies you are using the Password Flow. You would receive the error "Unsupported grant type" when the permission has been removed by the User on your application. 

Could you please provide the name of the RingCentral Application so that we could check and verify if that is the case. You can also email the details of your application to devsupport@ringcentral.com if you do not wish to expose the name of your application.
