The “Main Connection failed” error, when logging into the Web Service remotely, usually indicates that the TCP port has not been forwarded. If the error occurs on the LAN (locally) or if the HTTP and TCP ports have been properly forwarded, then try the following steps:
- On a video recorder (if using a network IP camera skip to step 3), go to Main Menu > Setting > Network and click the Network Setting button (if available). Make sure that IP Filter is disabled (unchecked). If IP Filter needs to be used, make sure the IP address that is accessing the device is added as a Trusted Site.
- In Main Menu > Setting > Network, check the Max Connections. If the Max Connections is set to 0, connection will be denied.
- Follow the Web Service log in screen is not responsive (Windows) article to reinstall the ActiveX plugin if applicable.
Make sure that the Ethernet cable is fully plugged in to the device and check the cable using a cable tester to verify that it is not defective. Check the device’s Ethernet port for dirt and debris as well as bent or missing pins.
