Issues with Firebase Admin SDK on elastic beanstalk

Just to give a brief introduction, I am using elastic beanstalk from Amazon to deploy my python (Falcon) application. I have two environments of elastic beanstalk (one being the main app server and the other one a worker environment). The worker environment receives HTTP requests for async tasks and then executes them. Most of the tasks are either push notifications (mobile devices) or sending emails. The strange part is that my tasks are failing with errors that I am unable to determine the cause for (this works fine for my local environment). Some of the tracebacks look like this:

AttributeError: 'NoneType' object has no attribute 'readline'

Some other exceptions are as follows:

ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:2570)
ssl.SSLError: [SSL: DECRYPTION_FAILED_OR_BAD_RECORD_MAC] decryption failed or bad record mac (_ssl.c:2570)
ssl.SSLError: [SSL: BLOCK_CIPHER_PAD_IS_WRONG] block cipher pad is wrong (_ssl.c:2570)

The code looks like this:

 message = messaging.MulticastMessage(
            tokens=tokens,
            data=data,
            notification=messaging.Notification(
                title=title,
                body=body
            )
        )
response = messaging.send_multicast(message)

This is quite strange for me since the tasks are failing and as a result, retrying. But somehow I am receiving multiple notifications. That means the notifications are being sent but the tasks are getting failed. Please help me out in understanding what could be the problem. Does it have something to do with the system date time?
