You might want to look into this message which you very well highlighted:
Error during task execution: Production Deployment, message: Could not retrieve CSContext for user: devadmin, locale: en_US, message: Invalid username/password combination. devadmin

Is devadmin a valid user? Is this a new user? After verification, try running a simple command line deployment logged in as devadmin.
