Download trusted root certificates
Resources of a webOS TV app provided as HTTPS should use certificates of which the root is one of the trusted root certificates. If the root does not exist in the list of trusted root certificates of the TV where the app is being launched, an Filed to load resource: net::ERR_INSECURE_RESPONSE error occurs.
The Let’s Encrypt certificate, which uses ISRG Root X1 as root, is supported from webOS TV 5.0. However, on webOS TV 3.X and 4.X, if the software update is properly performed, it is supported.
