Hi 

Last emby version - synonoly dsm 7.2

I ve got a problem since 2 month. 
I change my ip m3u, and since that i change adress in the emby app, the first time it took a lot of time to download canal and didnt work.
1 week later, it worked i didnt know why. 

and now again i cant read canals. canals disappeared. 

it worked 1 week ago, i could register tv, but not now. 

have u got an idea ? 
thanks !
