Getting Invalid resource owner credentials error regularly after some time when using acesss tokens to authorize ringcentral user. We are getting the access tokens by authorizing using grant_type=password. And are reusing the same access tokens for the next 1 hr to make API calls and then re generate tokens.
Using ringcentral java SDK version 1.4.0
We are facing this with ringcentral production credentials
@Phong Vu could you please help in finding the root cause?
