python ZeroRPC heartbeat error on public IP

I run a ZeroRPC server and I can connect successfully with a client to the 127.0.0.1 IP.
However when I use the public IP of the server to the client I get the following error:

zerorpc.exceptions.LostRemote: Lost remote after 10s heartbeat

I have opened the port from the firewall (using ufw on Ubuntu) but still get the same error.
Do you have any ideas what the problem might be?
Thanks!!

Solution

  • What IP address are you binding the server onto? If you want to listen on all interfaces and all addresses, something like tcp://0.0.0.0:4242 should work.
