Receiving 401 Unauthorized error, even if Hangups is authorized and functional

[Berulacks]

Trying to log in to hangouts via the app service, I'm receiving the following output/error:

======== Running on http://127.0.0.1:5000 ========

Thing is, Hangups itself works fine: I'm able to log in and chat without issue when simply running hangups. I'm using the same refresh token from ~/.cache/hangups/refresh_token.txt.

While troubleshooting I stumbled upon this hangups issue. I've ensured I'm running aiohttp>=3.3,<4 as per its requirements.txt, but still no luck.

I'm on Debian 9.8 and running python 3.6.8.

Anyone else having this issue?

I got this too, got around this error by using the code from hangups to login:

This makes the login to hangouts successful again except everything crashes for be now because I have old hangouts rooms in my matrix server and every time I restart the bridge it tries to connect more times and that causes database errors.
