Setup: Wallabag on Docker, Nginx reverse proxy, Https

Hey folks! Been reading and trying lots of suggestions found in the various Wallabag Github repos, tweaking nginx.conf etc, but I'm not able to get a consistent connection from the Android Client app. I assume this is an error with a reverse proxy config somewhere along the request.

When I first setup the Android app it works (intial sync, add 1-2 articles via share with Wallabag), then after adding 1-2 articles via Android, The Android client throws errors:

Android error:

Unknown error
wallabag.apiwrapper.exceptions.UnsuccessfulResponseException: HTTP response: 502 Bad Gateway
Stacktrace:
wallabag.apiwrapper.exceptions.UnsuccessfulResponseException: HTTP response: 502 Bad Gateway

Wallabag logs:

wallabag    | 2021/12/14 00:17:20 [error] 246#246: *67 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 172.27.0.1, server: _, request: "POST /api/entries.json HTTP/1.0", upstream: "fastcgi://127.0.0.1:9000", host: "removed"

Anyone able to provide any assistance? Thanks in advance!
