Can't add a specific channel

[zokayi]

When I try to add this Channel , the bot says "Can't find any videos"

Hi, it works for me. In general - you can add link for video, it will work too.

Hi, while it generally works, some channels do not. This is another example. I tried adding the channel url, the channel username, the channel id and some channel videos urls... nothing works.

Any other workaround or at least a possible explanation why some channels work and some others do not?
