Started last night. DC++ is stuck "connecting" all the time. Restarts of both router and Shareaza did not correct the problem. Everything else is working normally including web browsing and including Shareaza connecting normally to ed2k, G1, and G2 and able to upload and download files from these. Everything at my end points to it being the DC hub no longer accepting connections from me, but a) I haven't done anything wrong that might have provoked a ban and b) changing my IP address did not fix it. So there must be something my Shareaza instance is now doing wrong during the handshake that it wasn't doing wrong a couple of days ago.
What could be causing this and how do I put things back to the way they were on Wednesday?
