Hi all,

We are getting this error message after updating to the latest Rhino plug-in. Additionally, I cant see any active Rhino/Revit license under organizational account → License Pools page. Does anybody having similar issue today?

This is exactly what is happening.

> [PollinationIssue] I had someone working with it yesterday - I was able to see that he was using the license on the pollination license pool page. Now I am having issues with opening the license pool page and I am getting the error I attached when trying to retrieve the license.

PS:Solved!

Thanks,  
Levent

Hi @hlkocalioglu, see here:

> Hi @heikow and @maksym! Thank you for reporting the issue. The error code 91 is different and is because of an issue with the Cryptlex license server which is a service that we use for our license manager. I got in touch with them and they confirmed the outage and also confirmed that the issue has been resolved. Sorry about that. [https://status.cryptlex.com/780688531#logs](https://status.cryptlex.com/780688531#logs) We should develop a backup option to ensure any possible issues in their services don’t affect our customers.

Sorry about the issue. We should come up with a backup plan so Cryptlex downtime doesn’t affect you and the other customers. For now, it has been resolved.
