I'm sorry for opening an issue here. Because I do not know how to open new issue in your streamlink repo.

The script can work yesterday but today can not work. Then I tried GET https://nfc-api.nicochannel.jp/fc/fanclub_sites/{channel_number}/video_pages?vod_type=0&page=1&sort=-released_at&per_page=100 in Python.
The response data is {"error":{"message":{"fc_use_device":"MSGCM002"},"details":null,"debug_information":null}}. I also tried on another machine and the results are same. It may be the NicoNicoChannelPlus offical changed someting. But it can still get index.m3u8 in browser console.

After test, add fc_use_device in http header can fix this problem.

"python","-m","streamlink","--http-header","fc_use_device=null","--http-header","user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/109.0.0.0 Safari/537.36",url,"best","-o",file_name,]

Is there a way to add issues to a github forked repo (without modifying the original)? - Stack Overflow

Yes, the website has indeed changed something:

>curl "https://nfc-api.nicochannel.jp/fc/video_pages/smC69EkmRK7NLej4eWNnSj6F"
{"error":{"message":{"fc_use_device":"MSGCM002"},"details":null,"debug_information":null}}

>curl "https://nfc-api.nicochannel.jp/fc/video_pages/smC69EkmRK7NLej4eWNnSj6F" -H "fc_use_device: null"
{"data":{"video_page":{...

I'll add this header later and let you know.
