frigate: [Support]: View recordings in browser fails

Describe the problem you are having

Just installed Frigate (Docker ) on a Ubuntu 20.0.4 LTS running in VirtualBox on Windows, everthing seems to work excellent except that I can not view recordings in the webinterface. I get error message “The media could not be loaded, either because the server or network failed or because the format is not supported.” but the files have clearly been recorded and I have no problem viewing them with VLC.
