How can I force the public connector URL for broker registration behind a proxy

[trueg]

We run a DSC behind a proxy with a public connector URL for communication with other connectors. For setup and administration we use an internal network with the DSC API (imagine something like http://localhost:8080).

The problem arises when calling /api/ids/resource/update to register resources with the broker from the internal nextwork interface. The registration works properly but the broker will show the internal resource URL http://localhost:8080/api/... instead of the public facing one.

Is there a way to force the base URL for the connector during the registration with the broker?

Have you set the right default endpoint? https://international-data-spaces-association.github.io/DataspaceConnector/Deployment/Configuration#step-1-connector-properties
It is used to provide the external URL to the Metadata Broker.

Yes, the default endpoint is set in our config.json:

"ids:hasDefaultEndpoint" : {
      "@type" : "ids:ConnectorEndpoint",
      "@id" : "https://ids-dev.corpinter.net/mds/devportal/defaultEndpoint",
      "ids:accessURL" : {
        "@id" : "https://ids-dev.corpinter.net/mds/devportal/api/ids/data"
      }
    }

Does the default endpoint id also need to contain a uuid like many other resource URIs do?

no, it does not need to contain a uuid, the set value looks correct. This has nothing to do with the base url of the resources

You might be using an NGINX where you have to forward the domain as a header field to the application by adding following line:
proxy_set_header Host $host;
