Wildcard with rancher 2.0

Does rancher 2.0 support wildcart certificate?

we installed the cluster with a self sign, then replaced it later. And when we added ldap authentication we had problems with updating the cluster.

when we deleted everything an tried to set it up freshly with a wildcart we could not get the cluster up and running.

I use wildcard certificat without issue
If you have an intermédiaire certificat, then include it with the wildcard cert
