[SOLVED] env file is weird and WebsocketException

Hi guys, I am having trouble by configuring my self hosted appwrite server. If I connect via flutter to my appwrite backend - I get this error: "Unhandled Exception: WebSocketException: Connection to 'MYAPI:0/v1/realtime/realtime?project="some_values"&channels%5B%5D=account' was not upgraded to websocket"

There must be something wrong on the server side, because with the appwrite cloud - everything works.

Also I am a little bit concerned about the .env file, because by default it looks like this - and in the Docs is written, that some of these values are not default. Also f.e. I found nothing about this in the docs: "_APP_OPTIONS_FUNCTIONS_FORCE_HTTPS"

.env file:

_APP_ENV=production
_APP_LOCALE=en
_APP_OPTIONS_ABUSE=enabled
_APP_OPTIONS_FORCE_HTTPS=disabled
_APP_OPTIONS_FUNCTIONS_FORCE_HTTPS=disabled
_APP_OPTIONS_ROUTER_PROTECTION=disabled
_APP_OPENSSL_KEY_V1=some_values
_APP_DOMAIN=localhost
_APP_DOMAIN_FUNCTIONS=functions.localhost

I have changed the env file - so it is looking now like this, but this do not work either:

_APP_ENV=development
_APP_LOCALE=en
_APP_OPTIONS_ABUSE=enabled
_APP_OPTIONS_FORCE_HTTPS=enabled
_APP_OPTIONS_FUNCTIONS_FORCE_HTTPS=enabled
_APP_OPTIONS_ROUTER_PROTECTION=disabled
_APP_OPENSSL_KEY_V1=some_values
_APP_DOMAIN=localhost
_APP_DOMAIN_FUNCTIONS=functions.localhost

I have installed Appwrite 1.4.8

Thanks for helping

TL;DR

User is having trouble configuring their self-hosted Appwrite server. When connecting via Flutter to the backend, they receive a WebSocketException error. The issue seems to be on the server side since it works fine with the Appwrite cloud. The user is also concerned about their .env file, as some values are not default according to the documentation. They provided two versions of their .env file, but neither of them resolved the issue. The user has Appwrite version 1.4.8 installed. The problem was solved in a separate support thread linked in the original message.
