Hi! I haver migrate Qlik sense Server from 3.2 to Febrero 2018.
its all ok but, all days, there is an error in apps: "App migration failed".
In the txt log, there is a description about the error (or WARN):
Migration failed: Failed to connect a web socket against Engine: <no additional data>
If i export the app and import again, the error dissapear, but when I copy an app, the copy have the error.
Any ideas?
Thank you very much!
