Didn't realise i had a bug with this until i updated a cam with a new IP, it only affects new IP's added on port 37777 (could affect other ports but have not tested) and i ran a sniffer in the background which told me it read the IP (pinged it) but refused to log in, what has changed in this new SmartPSS 2.0 software? I literally had to update from the previous version cause the P2P were failing (As you know Dahua disabled the P2Pfor older SmartPSS and now when the P2P issue seems solved, the IP won't connect...2 cams i already had there on IP and port 37777 worked but not the new one i added, it pinged it twice and then refused to read it... whats changed and how do i fix i? thought it was my PC at first so i did the recommended DNS Flushing.. I had an older ICREALTIME software on my PC and Polyvision CMS and i tested the ip on both and they ran straight away so its not my net and i have no anti viruses on my PC and Windows Firewall is disabled so they are not blocking it.. Please Help..as per Previous posts i'm on Win8
