Zoom - YT (Can`t modify stream parameters)

[Jirisedek]

Hi guys, I face issue with Custom Stream Service.

In past I worked with CSS to YT and with every stream I could modify parameters as stream key and so. 
But now, when I just my personal meeting id as usual, it goes directly to invalid page and I cannot stream or modify paramets. When I push button, it automaticly start streaming to youtube but to invalid direction.

Any tips?
