cannot publish workspace after versioning it

[maaft]

First I did cargo workspace version to bump the version of all packages.

then cargo workspace publish fails with:

Current HEAD is already released, skipping versioning
error: config value `http.cainfo` is not set
info success ok

Also tried with --publish-as-is but that does not work with private registries:

cargo workspaces publish --registry private-registry --publish-as-is
error: config value `http.cainfo` is not set
error: crates index error: status code '401 Unauthorized': the request was not authorized

regular cargo publish works with tat registry. I'm authenticated and should be good to go.
