I get this error "Pi web API server could not be reached" on PI vision screen when i try to create Eventframe table. When i refer to docs there are many steps involved to configure security since it is coming under "CPT". I hope i followed the steps but still . It is mentioned in PI Vision 2017 R2 release notes that EF & XY plot is longer under CTP. (below snap).
How do i get rid of this error and get EF on the display.
