Thanks a lot for your notes and suggestions.

I've requested the free SSL certificate authorized by www.dnspod.cn
for my domain auto.hyddns.xyz, and now I can successfully play the HLS
stream with VLC through HTTP(S) published by the docker-nginx-rtmp
container. But I still see some error messages as shown below:

I'm not sure if these messages harm.
