Hello!
Get problems with clean installation  4.3.6.6-1.el7 and OVN

When i try to test OVN get notification:
«Import provider certificate»
 Do you approve trusting self signed certificate subject CN=Certificate Authority, O=SET.LOCAL, SHA-1 fingerprint a9d9b91160bb306667a521e6f2c66037ddc437cb?

 When i’m press «Yes», see old problem:
Failed to communicate with the external provider, see log for additional details.
