@TKb0iZ PeerTube servers have to do a lot of work to serve videos and/or may rely on third party services to do some of the work.These problems usually go away after a short while, but if they carry on it's a good idea to let the PeerTube server owner know as they may be able to tweak the settings to get it working better. There's usually a contact form on the "More info" link of a PeerTube server's website.
