Recently upgraded to 15.1.5 and some of our scheduled reports have stopped sending

Hello All,

Recently upgraded code levels and now some of our scheduled reports (both custom and standard) are showing in error for some of our Box Office Managers and Development personnel. They're having to go in and manually run the reports as the scheduled reports have stopped working. We have had our email server cycled and have had a ticket opened around the issue with Tessitura.

Has anyone else seen this with recent upgrades?

Thanks,

Nathaniel
