If network communication was working, but suddenly
stopped, the product's and/or computer's IP address may have
changed or is invalid. Try these solutions:
- Disable IPsec using the product control panel.
- If DHCP is out of date, or the IPv6 address is out
of date or was not obtained, you may not be able to find the IP
address registered in Web Config.
- If that does not solve the problem, enter a static
IP address using Web Config.
