ServiceRegistry accessible but not writable

[SebCanet]

Hello,
I have mounted a VM with local services (registry, orchestrator, authorization), without SSL for the 'insecure' mode. I manage to connect via the swagger-ui and create, delete what I want, everything communicates. But although the management tool reads all the information, it fails to write. I tried on my Arrrowhead sever, as well as Bologna one, I also tried with builded version, but same problem.

It seems that both the serviceregistry and the orchestrator do not allow access to the /mgmt.

The POST seems block on a security. Did I forget a parameter?
Thanks.
