LG WebOS error code -27 cannot seem to fix

[JurgenKuyper]

hello all, I seem to have the same issue as #60 ; LG app shows error -27, browser on that same tv works,
when using CURL on the domain I have the following output:

HTTP/1.1 302 Found

the first time I tried, I still had the X-Frame-Options SAMEORIGIN set, but removed it when it failed, the demo site works on the webapp.

pastebin of jellyfin nginx config
pastebin of nginx.conf

I have updated jellyfin to the latest version in apt, tv is also up-to-date.

I get the following in the access.log of NGINX:

if anyone knows how to fix this that would be greatly appreciated, thanks!
