Thanks NewManLiving -
I'm confirming the images are there in the browser using the same URL I'm getting from the channel debug output. In the app they fail with the "handshakefailed" error.
I now have the channel using roUrlTransfer to store the images in tmp:/ then pulling them up with TextureManager, but it seems to be slower this way. Testing on some other roku models to confirm.
But basically this tells me that, "yes roTextureManager is using the outdated TLS1.0 and won't get anything over https from modern CDN's that enforce security by requiring TLS1.2"
Now we are faced with using this slower method or switching to http:// or a less secure CDN that uses TLS1.0.
Or hope for a new roku firmware release tomorrow that resolves the TLS issues
