The customer who originally reported this issue disengaged from the investigation before a resolution was reached, and the root cause was never identified.

If you are experiencing the same issue and are willing to investigate further, we recommend opening a support ticket with the FactoryTalk Historian Connector vendor. If the product is still under support, their team can engage with us as needed to continue the investigation and help determine the root cause.
