First off thank you both for chiming in @TH2019 @nick.halliwell
1) I am signed in with the same account in iLok manager on both master and slave
2) Open your cloud session is greyed out on the slave PC (server 2019) Apparently only one session can be opened at one time?
3) Open your cloud session is available on the master but see a warning that a session is already open on the slave if I click on it
4) PT Artist always shows licensed in iLok manager
5) I logged into my slave machine this morning. I left VEP open and saw the Authorization Required: Vienna Ensemble Pro 7 message
6) No DAW was active on the master PC overnight
7) Shutting down and re-launching VEP on the slave machine gives me the License not found message. I exit, launch iLok manager, activate VEP again, re-launch VEP on the slave and all is fine. Moving back to the master PC in the control room, launching PT Artist am am immediately presented with the prompt: Restore your iLok session?
Forgive me for all of the screenshots. To say that I am frustrated at the moment would be an understatement. I feel like I have been running around in circles for a few days and getting nowhere.
