All methods return "Unknown method" error

[PhilipJFry2995]

I am using

• Windows 10
• deluge-2.1.1-win64
• WebAPI-0.4.0-py3.7

I have enabled WebUI and WebApi plugins.
Login works and I get _session_id in Postman

After that I try to get api version, but the result is

{ "result": null, "error": { "message": "Unknown method", "code": 2 }, "id": 1 }

my request is
POST localhost:8112/json
headers
Content-Type: application/json Accept: application/json

{ "id": 1, "method": "webapi.get_api_version", "params": [] }

Same for get_torrents

You may try to use the following snippet: https://github.com/idlesign/deluge-webapi/blob/master/webapi/test.py
Unknown method in common case designates that WebApi is not enabled.
In case of a client-server Deluge setup the note from https://dev.deluge-torrent.org/wiki/Plugins#Client-ServerSetups might be of help.

I also encounter this exact same error, machine specs, and circumstances are identical to author of issue

The likely cause, if the WebUI plugin is running, is that the WebUI itself is not connected to the RPC daemon.

Load the WebUI and connect it. This solved this for me.
