[DCP-o-matic] Encrypted DCPs/KDMs for Barco Alchemy ICMP?

Has anyone been successful in creating encrypted IOP or SMPTE DCPs for a Barco Alchemy ICMP? I have tried with 2.6.16, both in IOP and SMPTE format, SMPTE with Modified Transitional 1 and DCI specific. DCP and KDM is ingested successfully, and the interface shows them associated, the key validity window is displayed, properties shows 'valid' 'no errors'. I can load the clip into the player, but when I hit 'Play', nothing appears, the player claims it is playing, but silently goes to stop after 5s - this is the same for every variant I tried. I can play commercial unencrypted and unencrypted DCP-o-matic content without a problem. I also tried one time with 1.81, same result. We have not yet registered the certificate with a distributor or mastering service, so we have never received a commercial encrypted feature + KDM. Actually I was just trying to create a successful enrcypted DCP and KDM to test wether the certificate is working. Any idea? I have tried with both certificate downloaded from Barco database, as well as from the ICMP itself using Communicator.
