Root Cause
This error typically appears when:
The username or password submitted is incorrect.
The credentials are expired or revoked.
How to Resolve It
Double-check your credentials:
Confirm that your username, password, client ID, and client secret are accurate.
Avoid using your portal login password if you’re authenticating against SMPP or API services. Use the correct service credentials.
Check if credentials are expired or disabled:
Contact your account manager or support team if you're unsure whether the credentials are still valid.
