Issue in sending data to the server on openvpn - linux

Question

I have the following socket programming code. My client program is running on a VM on desktop machine using virtual box and my server program is running on a University cluster VM. The client is unable to send the data to the server. Both client and server program are running inside a docker container
running client and server container
docker run --rm -it -p 192.168.56.110:5555:5555 client bash
docker run --rm -it -p 192.168.101.238:5555:5555 server bash
client.py
context=zmq.Context()
print("Connecting")
socket=context.socket(zmq.REQ)
socket.connect("tcp://192.168.101.238:5555")
name="Max"
while True:
message=input("Message: ")
socket.send_pyobj({1:[name,message]})
message2=socket.recv_pyobj()
print("%s:%s" %(message2.get (1)[0], message2.get(1)[1]))
server.py
context=zmq.Context()
socket=context.socket(zmq.REP)
socket.bind("tcp://0.0.0.0:5555")
while True:
message=socket.recv_pyobj()
print("%s:%s" %(message.get(1)[0],message.get(1)[1]))
socket.send_pyobj({1:[message.get(1)[0],message.get(1)[1]]})

On the client side, its stuck its not sending the data to the server and on the server its not receiving data.
Help is highly appreciated thanks
