Hi all,   thanks for this work. We are using LE-Certificates for a some hundreds of sites. Up to now, we did not use them on the Traffic managers for 2 reasons: Clustering and GLB/DNS round robin.   As far as i read this conversation, the clustering problem has been solved, but didn`t make it into the script letsencryptforvtm, right? Our second problem is - how would you handle two or more clusters, that do not need to know about each other, but serving the same FQDN. You`d have to create the Cert on one node, distribute the challenge token to all other nodes in this cluster, as well as to the other cluster(s). When validation is complete, the certificate has to be installed on the other cluster(s).   Simple in theory, but is there any progress in this direction?   Best regards,   Ingo ... View more
