Migrate from Trello to self-hosted not public facing instance

I am trying to migrate from Trello to my self-hosted instance (on a physical PC) which is not accessible from the internet.

My publicurl is set to my PC’s name, since that make sense when using the instance internally.

My questions are:

  1. Which domain should I register with trello when I setup my app-key? According to the config.yml I have to use the same domain for the redirecturl.
  2. I thought Trello required that both an app-key and a token is used to connect?

My current migration config looks like this:

migration:
trello:
# Whether to enable the Trello migrator.
enable: true
# The client id, required for making requests to the trello api.
# You need to register your Vikunja instance at https://trello.com/app-key (log in before you visit that link) to get one. Copy the Personal Key and set it as the client id. Add your Vikunja domain to the Allowed Origins list.
key: “…”
# The url where clients are redirected after they authorized Vikunja to access their trello cards.
# This needs to match the url you entered when registering your Vikunja instance at trello.
# When using the official Vikunja frontend, set this to <service.publicurl>/migrate/trello (the default value).
# Otherwise, set this to an url which then makes a request to /api/v1/migration/trello/migrate
# with the code obtained from the Trello api.
redirecturl: “http://MACHINENAME/migrate/trello”

My log file gives me the following message:
level=ERROR component=http method=GET uri="/api/v1/notifications?page=1" status=401 latency=518µs err="code=401, message=missing, malformed, expired or otherwise invalid token provided"
