[kolla-ansible][Yoga] Install with self-signed certificate

Hi, To deploy Openstack with a self-signed certificate, the documentation says to generate the certificates using kolla-ansible certificates, to configure the support of TLS in globals.yml and to deploy. I am facing a problem, my old certificate has expired, I want to use a self-signed certificate. I backported my servers to an older date, then generated a self-signed certificate using kolla, but the deploy/reconfigure won't work, they say : self._sslobj.do_handshake()\n File \"/usr/lib64/python3.6/ssl.py\", line 648, in do_handshakeself._sslobj.do_handshake()\nssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED certificate verify failed PS : in my globals.yml i have : *kolla_verify_tls_backend: "yes"* Regards.
