Websocket

Deployment

I ran a streamlit hello page on a Ubuntu 24 server and tried to access it from local machine that was able telnet the server. The browser appears to be loading:

And the browser console keep getting this error
WebSocket connection to ‘ws://myserveraddr:myserverport/_stcore/stream’ failed: Error during WebSocket handshake: net::ERR_CONNECTION_RESET

Client Error: WebSocket onerror

This is my config.toml, i do not have a nginx proxy
[theme]
base=“dark”
primaryColor=‘red’
backgroundColor=“black”
secondaryBackgroundColor=“#000000”
textColor=“#ffffff”

[client]
toolbarMode = “developer”

[server]
enableCORS = false
enableXsrfProtection = false
enableWebsocketCompression = false
maxUploadSize = 1000
maxMessageSize = 200

[browser]

Does anyone know the solution or experieced similar problem?

Hello,

Is your app running on the local server ?

Are you running your server on VM ?

I get this kind of errors when trying to connect to a closed port of a server running on VM.

I hope this helps,
