Hello, I am trying to subscribe to a channel using Realtime in my flutter app. I have the following code:
var sub = realtime.subscribe(
["databases.main.collections.teachers.documents"]);
And then have a function which simply calls sub.stream.listen to listen. When I launch the app, I only get the WebSocketChannelException and in the devtools console of my browser I get can’t establish a connection to the server... and that the websocket returned an error 400. I tried to look into the appwrite-realtime container logs and it simply listed Connection close: N over and over. I am pretty sure the realtime endpoint is correct and the collection has its collections permission currently set to allow anyone to read. But I still cannot figure out where is the problem.
TL;DR
User is having trouble subscribing to a channel through Realtime in a Flutter app. They are receiving a WebSocketChannelException and a WebSocket error 400. They have checked the appwrite-realtime container logs and the collection's permissions. They are using Nginx, Plesk, and Cloudflare as proxies. The solution suggested is to check if websockets are enabled in Nginx and if traefik trusts both proxies.
