mautrix.errors.request.MUnknownToken: Unrecognised access token

I'm sure I followed the instructions pretty thoroughly, but still getting this:

# /usr/local/bin/heisenbridge -c /etc/matrix-synapse/conf.d/heisenbridge.yaml -p 9897

The generated yaml file should be ok.

Perhaps moving the yaml to a different place. If you're using split Synapse config files, there are two files involved, one generated by heisenbridge, and one Synapse needs to load the former. Mine was:

app_service_config_files:
  - /etc/matrix-synapse/appservices.d/heisenbridge.yaml

So Synapse loads everything in /etc/matrix-synapse/conf.d/ as Synapse config, but the Heisenbridge config file isn't that.

I've tried using @lnicola's approach without success (Synapse server running on NixOS + heisenbridge inside a docker container with --network host)

Also tried @lnicola's approach. Same error.

Okay, so re-read the README.md. It assumes too much, somehow skipped the part 4, "Add heisenbridge.yaml to Synapse appservice list". I had no idea how this happens, so here is how, based on this (also bad documentation imho).

sudo nano /etc/matrix-synapse/homeserver.yaml

Search for app_service_config_files, if no such settings, add to bottom:

app_service_config_files:
  - /etc/matrix-synapse/conf.d/heisenbridge.yaml

Restart Synapse:

systemctl restart matrix-synapse

Then the command should work. Or use a systemd service or whatever. Works now for me so I can close this issue.
