No data coming from server

[MaJunior420]

Hello, I am running the mix run --no-halt command (mix deps.get ran with no issues) and immediately receive a bunch of WARN level logs messages. The server process does start and connections to the server are seen in the output but no data appears to come though to the client.

Below is some of the output I am getting.

I'm not sure if this is related in any way to not receiving any data as that could be another internal issue entirely but it would be nice to get some more information on what these WARN log messages mean and perhaps how to resolve them.

Thank you.
