Unable to connect to indexer

I’ve been using NzbDrone for awhile now with no issues. All of a sudden I’m getting errors saying unable to connect to my indexer. I’ve been using Nzb.su Please see the following error.

System.Net.WebException: Unable to connect to the remote server —> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:50354

Any help would be greatly appreciated. Thank you in advance

There is a proxy on your system handling the traffic, its either something you setup or came from a virus, scan your system with a few different tools and remove all traces.

Thank you for the quick reply. I don’t see any proxy’s setup. I’ve ran malwarebytes and combo fix with no errors or viruses found. Any other thoughts?

where did you look for the proxy settings? whats your OS?

Proxy settings are in the Internet Options, connections, lan settings. I’m on Windows 7 Pro 64bit. I did some more testing last night and it’s definitely something with my PC. I installed on a spare laptop and worked fine. I’ve ran multiple Virus/Malware/Spyware scans and nothing has popped up. I’m at a loss currently

whats listed in this registry key?

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]

that looks ok it doesnt appear to be enabled

do a system restore back to a point when you know it was working?
