Hi there,
I'm running a flask app on port 5000 and a websocket server on port 8080. I'm running into issues with exposing both ports. I find that if I set the railway subdomain to port 5000, the flask app works but connecting to the websocket gives me this (Telnyx) error:

ERROR:app: Failed to start streaming for call v3:OIsW2ZYahZ8RR3TaqtA5dvPm-JFN6DEdnlVXhg_yzn0UNr1VOHbt-w: 422, {
"errors": [
{
"code": "90046",
"title": "Media Streaming failed",
"detail": "Failed to connect to destination"
}
]
}

Essentially the issue is a matter of exposing multiple ports. I tried setting the websocket server to point to a TCP Proxy link, but it gave the same effect. Assumingly because Telnyx couldn't connect to the proxy link and was falling back to the subdomain that points to port 5000.
What's the issue here? Can I utilize the TCP Proxy setting, or would you recommend I buy and set a custom domain? (So subdomain --> 5000, custom domain -> 8080)
