Thank you Alexander for the additional information. I noticed you are using Ubuntu 20.10. Is the missing subdomain problem you are observing a regression of Ubuntu 20.10, or is the problem present even with earlier version of Ubuntu (e.g. 20.04 LTS)?
Setting up a reproducer for this kind of issue is not straightforward, and bounding the problem to a change happened between two releases helps the search for a possibly breaking change.
