@T.Golbach There has always been a limit in CML sandbox reservations, per the teams comment here https://community.cisco.com/t5/devnet-sandbox/active-environments-launched-from-this-blueprint-reached/m-p/4976470#M9010
”This has always been a challenge for a free service like ours. Our limit for CML reservations is the same as it was before our migration. I agree that the lack of a scheduler can frustrate this even further but we do have plans to up the capacity and make this less of an issue”
Your options are, wait like everyone else’s has to or use another free service.
Hope this helps.
