Why is the built-in metadata not working for my program's media library?

Do you have access to TVDB or is that site blocked as well?  OMDB?

Have you considered using a VPN to gain access to these databases?

It is my understanding that Jellyfin only supports some text formats for reading NFOs.  Can you attach some sample NFOs that TMM generated?  Use "New Reply" instead of "Quick Reply" to get the option to attach files.

thanks for replay，
I haven't tried TVDB and omdb yet. I don't have experience deploying to nas server for vpn, so I'm not very good at it.
I set nfo to "generate jellyfin format" in tmm settings, and I checked that the name of nfo in the folder is tvshow. nfo,I took some pictures from the tvshow folder, and then uploaded an nfo source file, hoping to help.The NFO file type does not support uploading, so I saved it as txt。
