Do you know why the monitor was using port 7023?
As I know, Axon's WebSocket port is 8010 by default.

As I know, WebSocket port is Https port plus 1, it's hard-coded in the test case @jjyr

WebSocket port is Https port plus 1,

Why?

You can see that the default config of Axon is

[rpc]
http_listening_address = "0.0.0.0:8000"
ws_listening_address = "0.0.0.0:8010"

https://github.com/axonweb3/axon/blob/6fe5777e0b4a9b994dc84a56a00005745fd05085/devtools/chain/config.toml#L7-L9

It is not related to Axon default ports.

In IBC test framework, the framework generate random ports for each protocol, except for ws, IBC framework using the same port for http and ws.

Unfortrunately, Axon do not support listening http and ws on the same port. So we make an adjustment to always use http + 1 as the ws port. This assumption only affects the tests.

I think we already discussed this issue in c7e22e7

Should be fixed in #332
