CloudFront m3u8

Question 1 CloudFront proxies m3u8, and origin is very slow. How should CloudFront be configured, for example, connection attempts, connection timeout, response timeout, keep-alive timeout, shortest TTL, longest TTL, and the default TTL values, to ensure smooth playback of m3u8 for users without buffering.

Question 2 the website is Openresty ,cloudfront proxies m3u8 ,show 401 Authorization Required, How should CloudFront be configured. Thanks.
