Anyone having issues with "Remote Desktop License Issue" error messages?

A month or 2 ago our ticket office starting getting blue pop up screens titled "Remote Desktop License Issue". The message would go on to explain that their time in Tessitura would be limited to 60 minutes until the issue is resolved. It was rare and sporadic at first but just today, almost every single ticket office user got that pop up and was kicked out of Tessitura. They can usually switch browsers and that corrects it at for a time. We have an open ticket with Tessitura but haven't seen a resolution yet. We also don't want to ignore the possibility it might be an issue with our organizations computer/network. I know as university affiliated organizations our IT protocols are a bit more complex than some other organizations. So I'm wondering if any other fellow university Tessitura users have experienced this issue and if so, did you find the issue to be with your organization/university's IT systems or with Tessitura?
