It seems your video won't play. It just says "video is unavailable to view".

I do not understand if the video looks something pixelated but you can see perfectly.

perhaps the video is set to private which makes it unviewable to others, try just setting it to unlisted if its on youtube or publish it to be viewed by all. If it's on twitch and its a vod rather then highlight perhaps it longer exists... since after around 14 days vods are removed.

checked the submission and I can now see the video.

Verified.
