Hi, For the above error, I would make sure to use a ping query in the [Connect Pool Configuration]( of the cache datasource. I would recommend you to review the VDP log and Scheduler log files for further details, looking at the error it looks like the connection has been terminated by the cache datasource(host). Additionally, if you still need help and if you are a user with valid Support account, you may open a support case at the Denodo Support Site and the support team will help you. Hope this helps!
