Error 403 Forbidden

[Shinmera]

I tried running this, but every action results in a 403 error. I set up a new admin account specifically for this, verified that it can log in with the provided password, and also verified that it is indeed an admin using synadm. I also made sure the as_token is the same as in the migration_service.yaml, and that that file is referenced from the homeserver.yaml.

The homeserver log file shows each request from the script with the following message:

SynapseError: 403 - Application service has not registered this user (@shinmera:matrix.tymoon.eu)

Which is slightly confusing -- the user should be shinmera:tymoon.eu. The instance is only hosted on matrix.tymoon.eu. In the config.yaml I made sure to set the domain to tymoon.eu. Not sure if this is the source of the error, or what else is going on.

Any ideas or help would be appreciated!
