Cannot start collaboration 14

Teima — Wed, 28 May 2025 12:26:35 GMT

Hello All,

I cannot start Collaboration 14 with disabled lunch button with the following message:
"The maximum number of concurrent environments for this blueprint has been reached. Please try again later."

I haven't created any instance before, is there an issue with the instance itself or should i do something?

Regards,

@Teima sandboxes have limited amounts of reservation which can be made. The message you see, means all current reservation are in use. The sandboxes operate on a first come first served basis, this just means you have to check back later when one is free to reserve.

Hope this helps.

How do we know when one frees up? Is there any type a waitlist or notification that can be setup? Or do we just check back every ten minutes indefinitely and hope that we accidentally stumble into one with availability?

@Uriah Erter i dont think there is sadly, it is just a case of checking back.
