The AF databases could not seem to crawl in PI Vision. As you can see the attributes from the databases of the AF could not be seen.
But if you would see the configuration from the Administration view it could connect to the AF Server, but could not index the databases.
We've tried almost all the solutions we found online. We've already ran the OSISoft.REST.Admin application still no luck. We've also tried running the AF Diagnostic tool for reindexing and recreating path cache. I've also tried restarting the services (Web API, Crawler).
What could be the possible root of the problem?
