No actual bridging happening at all

[F13]

I had a problem with the bridge no longer sending/receiving any messages. I attempted to reinstall multiple times. I can see events firing in the logs when I send a message in Matrix as well as when I receive one in Hangouts, but nothing is communicated between the two services. The only error I can find is immediately after login:

After this error I continue to see regular log updates, including what appear to be Hangouts events, including:

            underline: false
          }
        }
      }
    }

and others.

I have tried completely removing the mautrix database and restarting the docker container from scratch and I still get the same result. Aside from the one error noted above, the log makes no indication whatsoever that anything is amiss.

Any thoughts?

This seems to be something hangouts changed, other people are also reporting it: tdryer/hangups#498

Probably need to fork/update the library to retry on 401 or something

Switched to a fork of hangups in 826c127
