I have created a torrent but when i try to upload onto a site i keep getting failed due to “dictionary missing key (s)”. Can anyone help please,
Thanks in advance 
what site r u trying to upload to?
AFAIK all site doesnt support trackerless torrent so make sure u use the right tracker…
While you are creating a torrent, you must specify the (correct) url of the tracker you will be uploading that torrent to.
