TAC I/A Series
I/A Series R2 (Niagara) Enterprise Server, all versions.
These errors are related to invalid subscriptions (swids) typically caused by changing the parent container or object name on the UNC without deleting and recreating the associated external link. The swid name changed but the external link is still referencing the invalid swid.
Review the links specified in the error message(s) and correct them.
