I am having the same issue with Sencha Cmd 6.5
appCache is disabled, yet still I get this warning in a production build in the latest Chrome, which is very annoying!
Code:
[Deprecation] Use of the Application Cache is deprecated on insecure origins. Support will be removed in the future. You should consider switching your application to a secure origin, such as HTTPS. See https://goo.gl/rStTGz for more details.
