@jumpipi for now we have to resort to manual upload, both QTM and GUU are defunct because of the new cloudflare barrier in the login page. if you are trying to upload a file/folder that is less than 8GB in size, you can use the upload page to create the torrent file on the fly. but if your total files go beyond that size you need to create the torrent file beforehand using your torrent client.
since you mentioned you are already seeding the torrent, can you check the tracker tab to see if you have the proper announce URL or if there is a status message?
If you see this URL in your tracker's tab, it will not work: http://gaytor.rent:2710/announce
The tracker URL must look similar to this: https://tracker.gaytor.rent/eg155nmsebyvcpcgmt0t11wdpygpn5mu/announce
