Also Just tried to use the cloud CMS to make sure my docker instance had any issues. Even from the cloud instance the Text, Countdown widgets did not work. I tried Verify All for modules as well.
Please find the log errors from the Player below,
XFA:WebView onReceivedError: http://localhost:9797/6_12_12.html, Code = -1, Description = net::ERR_CLEARTEXT_NOT_PERMITTED
Thanks and Regards,
