Error while saving Live TV configuration

[ski007]

I created an .m3u list with TV channels (DVB-T2) in the Tvheadend program, which is also on the same PC with the Jellyfin server :-)
A standard command in a web browser to the Tvheadend server, after which we receive a .m3u list

Code:

http://IP-server-Tvheadend:9981/playlist

I tried adding my TV-DVBT2 to Jellyfin also with the tvheadend v12 plugin. I would have everything in Jellefin ... but nothing wants to work, it only shows TV recording files which, after starting, have a time shift of the sound ... I will probably give up the TV option on Jellyfin because direct playback from an .m3u file in another program works very well for me yes on PC and Android.
