Here's what I'm doing on Transmission:

-Create New Torrent
-Add tracker address https://mma-torrents.com/announce.php, clicking on the private, and create torrent files (I don't open the torrent right after I create it)
-Upload it on MMA-Torrents
-Download new Torrent files
-Make sure I allow connection by using Little Snitch
-Load new Torrent on Transmission, then nothing is happening, it stays at 0%

Any help?

Hi,

You deleted all the uploads you made so I cant see what the problem can be from here.

When you say "it stays at 0%" what do you refer to?

I just created it again.

I'm referring to the new Torrent files that I'm downloading through MMA torrent.
When I load it on Transmission, there is no movement, not a single download.

Alright! On the torrent you show as leeching it instead of seeding it so I suspect you do not have your passkey on the announce url in your client. Try adding the announce url with the passkey from another torrent you downloaded successfully and see if it starts to seed when you do. Just copy paste it to the new torrent.

Right-click the torrent > Properties > Trackers > Edit

There is no right click Properties/Trackers/Edit on transmission.

Do we agree that I don't have to load the first Torrent I created on my Transmission, correct? I only create it to upload it on MMA-torrents.com, then I only load the new Torrent in Transmission?

After creating the torrent it should already be in your torrent list in Transmission. After adding the .torrent file you created to the site, and after it is uploaded and when you click download torrent on your own uploadand open the downloaded .torrent file in Transmission it should ask if you would like to add the tracker, if you click yes it should start to seed.

If it doesnt add the trackers for some reason you can always do it manually.

Just use Google to find how to edit the trackers in your client. I found this when I Googled

...but maybe its not correct? If not, use Google to find the correct way of doing it for your client.

If you double click the torrent in Transmission, is there a tab called "Trackers"?

So I was able to change the passkey

But when I try to load the new torrent files (the one download on MMA-torrents) it says it can't be loaded because there is already a duplicate.

Do not ever post your passkey publicly! I have removed the sensible info. Please reset your passkey from your profile settings and then update it with the new passkey on your torrents.

Thank you very much, I finally fixed the problem! (I ended up not uploading new torrent, and only updating tracker passkey!

Sorry for the disagreement !
