SOLVED: I can't access from LG TV with Caddy

[Drake97]

The "SAMEORIGIN" head is problematic specifically for WebOS.  But only if you use the WebOS app.  If you used the web browser in WebOS, SAMEORIGIN would not be a problem.

I have arrived, sorry for the late reply.
With the modification you gave me of my caddyfile, no more problems on LG TVs, even without having activated SAMEORIGIN, all devices still see the featured-content-bar what I find strange, but well, everything contributes and are pure good news.
Thank you very much as always
