Hello everyone!

I've been trying, for hours, to get Realtime to work in my Flutter App (for a client). The subscription always fails, logging this to the console:

I/flutter (25446): Reconnecting in 1 seconds.```

As far as I know, that ":0" isn't supposed to be there.
I've triple-checked my Endpoint and it is correct.

My AppWrite instance is self-hosted, on my VPS.
These are my Apache directives:

Preserve Host headers and set X-Forwarded headers

ProxyPreserveHost On RequestHeader set X-Forwarded-Proto "https" RequestHeader set X-Forwarded-Port "443"

Enable WebSocket Support

RewriteEngine On RewriteCond %{HTTP:Connection} Upgrade [NC] RewriteCond %{HTTP:Upgrade} =websocket [NC] RewriteRule /(.*) "ws://127.0.0.1:8080/$1" [P,L]

WebSocket location for realtime

ProxyPass "/v1/realtime/" "ws://127.0.0.1:8080/v1/realtime/" ProxyPassReverse "/v1/realtime/" "ws://127.0.0.1:8080/v1/realtime/"

Forward everything else (Appwrite Dashboard and REST API)

ProxyPass "/" "http://127.0.0.1:8080/" ProxyPassReverse "/" "http://127.0.0.1:8080/"

A cURL command I used to check functionality:

curl -i -N
\ -H "Connection: Upgrade"
\ -H "Upgrade: websocket"
\ -H "Host: appwrite.danfq.dev"
\ -H "Origin: https://appwrite.danfq.dev"
\ "https://appwrite.danfq.dev/v1/realtime?project=bubbl&channels%5B%5D=databases.main.collections.winks.documents"

The response:

HTTP/2 400 server: nginx date: Fri, 11 Apr 2025 16:56:00 GMT content-type: text/html; charset=UTF-8 content-length: 83 cache-control: must-revalidate,no-cache,no-store

Any ideas? Thanks in advance!
