We just solved this problem in the chatroom for somebody. She was having the same issue. Wrong IP. I've seen this before when satellite internet has been used and that's what she had. Satellite internet. Here's what's happening in that situation.
Satellite based internet only downloads from the sky. The upload is sent through a land line. Consequently, this gives people a different IP for their downloading and uploading. In most cases, the isp solves all the technical details behind one connection having two IP addresses, but when it comes to file hosts it cannot. The file host reserves a download slot for the IP that requests it. When the download begins from a different IP it won't allow it.
Here's the solution for this case. Use a free VPN. It may be slow but at least it works. By using a VPN, the file host sees only one IP and all that upload download connection bologna is hidden by the VPN. Two free VPN services that are easy to set up and get working that I recommend are Hola
and Hotspot Shield
. This solved it for the person using satellite internet. I dont know what your situation is but it may work for you as well. Good luck!
