Yes, after the upgrade of the ansible.netcommon collection (which is used to connect to the SMS I assume) I can't run anyone of the mgmt collection tasks anymore. They exit with a HTTP 415 response during the login action.
For reference this the API log with the upgraded ansible.netcommon. With just going back to 4.1.0 it works again.
