23 Troubleshooting
Symptom
Cannot access from the web browser.
Cannot access the camera via the Internet.
Cause/solution
•Is “554” selected for the HTTP port number? For the HTTP port number, select a port number other than the following port numbers used by the camera. The number used by the camera: 20, 21, 23, 25, 42, 53, 67, 68, 69, 110, 123, 161, 162, 443, 554, 995, 10669, 10670, 59000 - 61000
•Is the same IP address provided to other devices? Are there contradictions between the address and the network subnet to be accessed?
When the camera and the PC are connected in the same subnet:
Are the IP addresses of the camera and the PC set in a common subnet? Or is “Use Proxy Server” for the settings of the web browser checked?
When accessing the camera in the same subnet, it is recommended to enter the address of the camera in the “Don’t Use Proxy For These Addresses” box.
When the camera and the PC are connected in the different subnet:
Is the IP address of the default gateway set for the camera correct?
•Is the name currently used to access the camera different from the name registered for the “Viewnetcam.com” service?
Access the camera again with the registered name.
•Did you access “http://” while using the HTTPS function?
To use the HTTPS function, access “https://”. It is also necessary to enter the port number.
•Are the network settings of the camera correct? Set the default gateway or DNS server address correctly. To use the DDNS service, check that the settings are correct.
•Is the setting for “Default gateway” on the “Network” page configured? Or is the setting correct?
When communicating using IPv4:
Configure the setting for “Default gateway” of “IPv4 network” on the [Network] tab of the setup menu.
