SSDP communication not working between VMs

Just trying to make an app which can discover other instances of itself over the network.

Was trying to run ssdpy python package quick start example. I run the following command in one machine:

$ ssdpy-server my-special-service --location ''

Then I run the listener command from another machine:

$ ssdpy-discover ssdp:all 

The above command does not list anything. There are no execution errors.

However on running both server and client on the same machine works. It is some networking/standards issue; but can’t figure what is the issue.

Hi there,

In case both of your servers are running in the same VPC, I would recommend changing the address from to match your actual server private IP address.

Then to check if the service is actually listening on that port, you could run the following command:

netstat -plant | grep 8080

Let me know how it goes. Best, Bobby
