Federated User with port# at the end of the address does not work with circles

Dear All,

im running a NextcloudPi behind a Fritzbox. In order to have it accessible from the Internet portmapping is enabled.

I can add a federated user like <user@xxxx.myfritz.net:#portnumer> for sharing within a hosted nextcloud instance and do have access to the shared objects within the PI nextcloud instance behind the fritzbox. So thats fine.

Next step is to create circles. Adding a user in the form of <user@xxxx.myfritz.net:#portnumer> is not supported by the circles app.

However, without the portnumber the user cannot be found (obviously).
Is this a known problem? Any workaround you would suggest?

The issue reports that Circles rejects federated users written with a port number, while ordinary federated sharing accepts them. No source file, test, reproduction steps, or entry point is named; start by reproducing the user lookup in the Circles app and compare it with the working federated-sharing path. Done means a federated user with a port can be added to a circle and access shared objects.
