- Go to the VLC installation directory.
- Look for the file named lua/extensions/VLSub.luac.
- Open that file in a binary or hexadecimal editor. (Notepad++.)
- Look for the character sequence “HTTP/1.1” (without quotes).
- Replace the last one by a zero: “HTTP/1.0”.
- Repeat the procedure; there should be a second occurence in the file.
- Save the file.
- (Re)start VLC.
