Handling video with Friendica

Hello , it's me again 😀

today i was about to upload #video to my #friendica account , but figured no possible way to do this.

When i'm about to upload file, i get "bad request". I also did not found the way to upload it into "files section".

Embedding from #youtube also does not work for me.

Is there any way to use video in posts in friendica at this moment?

Thanks
