API access gets 400 with swag reverse proxy

[Herschdorfer]

I have configured the settings as followed:

    "openhab.connection.host": "openhab.****.or.at",
    "openhab.connection.port": 443,
    "openhab.connection.authToken": "oh..."

I use docker with a SWAG instance for reverse proxying and I can reach the API from the same machine on Chome via https://openhab.****.or.at/rest/.

Expected Behavior

API access in VS Code.

Current Behavior

I keep getting http 400 failures.
