bug description

My internet connection speed exceeds 100 megabytes per second. Previously, Cobalt uploaded the necessary videos at high speed. Now, besides the fact that the download speed is at the level of 100-200 kilobytes, it also drops to 0 kilobytes per second, and the video starts over. I often use your service to download the necessary videos. I upload one video at a time, I'm not a bot, and I seem to be doing everything right. I don't understand why there weren't any problems before, but now they have appeared. That's why I leave relevant feedback. I fill out the template correctly and attach screenshots.
