I'm having trouble with every video file on my server. I use firefox, if I double click the file, it comes up with an error "no video with supported format and mime found. If I download them, the file size is 0. In file list, they do have proper thumbnails and correct sizes. I can play them if I download the file using ftp. Filerun is on a Ubuntu 18.04 server with Apache2.
