How to notify a python client from node server?

I have a node process which is currently receiving POST requests at https://company/api/bats_hook/, I want to notify a python process whenever a job comes in, am using node_redis and redis-py, the implementation looks like below.

Following code works great locally when the node process is running locally ,when i push the node endpoint to a server ,I dont seem to get the events?how do I subscribe to the endpoint on the server from python client?what is missing?I do have the redis server deployed on the server

https://company/api/bats_hook/

// javascript
var redis = require("redis"),
//redisClient = redis.createClient();
redisClient = redis.createClient({url: process.env.REDIS_URL});

app.post("/api/bats_holder", (req, res, next) => {
  console.log(req.query.params)
  console.log(req.body)
  console.log(req.body.name)
  // This publishes a message to the "bats hook channel"
  redisClient.publish("bats hook channel", JSON.stringify({
    params: req.query.params,
    body: req.body,
  }));
  res.status(200).json({
    message: "BATS object",
    posts: req.body
  }); 
});

python

import redis

r = redis.Redis()
p = r.pubsub()
p.subscribe('bats hook channel')

# This blocks and reads any messages from the "bats hook channel" as they come in
for message in p.listen():
    print(message)
