rory 0 Posted February 8, 2011 Did you port forward to the DVR's IP in the router? Share this post Link to post Share on other sites
kez1985 0 Posted September 21, 2011 Bump! I have exactly the same problem, I have set up the ports to be forwarded to the dvr but the web interface still gives me this error message. If anyone could help with this it would be great. Cheers, Kerry Share this post Link to post Share on other sites
SEANHAWG 1 Posted September 21, 2011 Your ports are not open. Go to the same network that your DVR is in and go to the website canyouseeme.org and check to see if your ports are open. They are more than likely being blocked. Share this post Link to post Share on other sites
atuld 0 Posted April 14, 2013 Dear, Your Web Port is Open and TCP Port is Closed, so the error "failed to connect the device in main connection" occurred. Share this post Link to post Share on other sites

ScottS 0 Posted December 29, 2013 Try inserting the DVR IP address in the (DMZ) of the router. that will place it outside any protection or firewall the router my have up. If it works there, the you have a port issue or firewall issue. Share this post Link to post Share on other sites
