To confirm if it is a BI or CP.AI issues open up CP.AI Explorer and run a test, if it works using CP.AI Explorer then its a BI issues.Thanks for the update. I installed 2.1.8, following the above instructions. Running the most recent version of BI (5.7.62), and get nothing but AI Error 404. I'll roll back BI to a previous version I know worked better and see what happens.
