## Thinkific Connectivity Issue During the morning hours of August 13, 2021 we received a number of reports that assessments launched from Thinkific sites were displaying an error message of "Invalid Access Code". This prevented students progressing further. ### Investigation We opened an investigation and found no issues with the Brillium software services. We followed this action by notifying the Thinkific Support team. Shortly thereafter we were notified that Thinkific Support was working with their Development team to investigate the issue. ### Fix We were notified that Thinkific Development team had applied a fix towards the end of the day on August 13, 2021. We were no longer receiving reports of the problem. ### Monitoring As a matter of process, we monitored activity for 18 hours following the last reports. During this process we reviewed support cases, error logs, and continued to monitor activity. ### Root Cause As this was an external issue stemming from activity coming from a third-party system, we are unaware of the root cause of the issue or the fix applied. From our own internal investigation it appears that there was an issue with the student data sent from Thinkific to Brillium. **NOTE:** This was **NOT a Brillium issue** and had no impact on Brillium operations or availability. This was an external problem with a third-party system that affected a significant number of our Thinkific users. As such, we investigated the issue and report the status and findings as a convenience to our customers.
