I'll assume you are meaning you are trying to get a torrent file you created cached by Real Debrid?
If so, make sure you have port forwarding setup correctly. Since you made the file, you would be the only seeder so you must have port forwarding. Use an online port checker for example and see if they can reach you on your torrent port while it runs.
Another thing to check is make sure you included a public tracker or two while creating the torrent so RD can find you (assuming your port is forwarded correctly).
