audb might fail to access data if a repo without access is stored on the same host about audb

This is not only affected by repos without access right, but also by empty repos. Maybe they connection is not closed when trying to access it and this lets the next connection fail?

This cannot easily solved by adding some waiting time before redoing the request as we might have independent calls to audb on the same machine.

In case that waiting will turn out as the only option: openai has a nice tutorial on expontential backoff as a waiting strategy here. Their usecase is API rate limits but the problem is very similar. They even provide a handcrafted decorator that should be easily adaptable and can avoid external dependencies.

Would be nice if we can have instead a way to first ask Artifactory if access is given for a repos and only try to access the repo if this is the case.

This SOV post suggests that it might be possible to get this information without doing a full audb.get.
