I am attempting to trend a few tags using a perspective power chart and core historian. The power chart constantly flashes “No Trend Data Source available” attempting to reload, but can’t find the tags. Every ~30 sec, the correct data will very briefly display, but then it is replaced by cycling no data message. In checking the console log, I see that a 403 error message is generated each time the power chart attempts to reload. I see the same behavior in the designer, but aren’t provided any error messages. No errors visible on the wrapper log either.
Does anyone know what may be causing these 403 permission errors?
