Integration Works Locally, Deployment is Throwing java.util.concurrent.TimeoutException

I'm having a problem with an integration once deployed, but it works locally. The structure of the integration looks like this

Database SAPI <-> PAPI <-> SFTP SAPI

The PAPI calls the Database SAPI and the Database SAPI calls a stored procedure and compresses the result. Then, the PAPI sends data to the SFTP SAPI, which writes the data to an SFTP file location.

Once I deploy, I'm getting this error in response from the SFTP SAPI midway through execution of the integration. Can anyone help me narrow my issue down?

HTTP response sending task failed with error: java.util.concurrent.TimeoutException
