When playing youtube videos, the thumb cannot be displayed

Do I need to add some configuration? I see that there is yt-dlp related processing in the code, but it does not display
I use the default configuration of uosc
Local videos can thumb correctly

./mpv.com 'https://www.youtube.com/watch?v=Ugb80d5lxEM'

You need to enable network, https://github.com/po5/thumbfast?tab=readme-ov-file#configuration

After changing the setting network=yes, a white image is always displayed.

A minimal reproducible structure, only one script is installed, and the default configuration only changes network=yes, but thumb is always white and no error in the terminal

To avoid network problems, I turned off the VPN and played a bilibili video. The same thing happened.

 ./mpv.com 'https://www.bilibili.com/video/BV1Ba411g7EC'

mpv.conf

script-opts=ytdl_hook-ytdl_path=./portable_config/yt-dlp
ytdl-raw-options=cookies=./portable_config/cookies.txt,mark-watched=

I have this same problem when codec is vp09. When I switch to avc1 thumbs generate.
