Description

@sep76

I am running dock.mau.dev/mautrix/googlechat:latest
i normaly use the chromium plugin for the google chat login-cookie and it have worked flawlessly.

but a few days ago, all google loging failed and trying to login again leads to

Google Chat bridge bot
Those cookies don't seem to be valid

have google changed something in their authentication recently ? is this a common experience ?
