If the IP channel is not connected, the device or network cannot connect to the IP channel properly, resulting in data transmission or network resources. To resolve this issue, you can follow these steps:
Check the network connection: Make sure that the network connection of the device is normal, including checking whether the network cable is plugged in properly and whether the network equipment (such as routers and switches) is working properly.
Check the IP settings: Check whether the IP address, subnet mask, and gateway settings of the device are correct. The IP settings can be checked and modified by viewing the device's network settings or by using a command-line tool such as the ipconfig command.
Check the firewall settings: The firewall may block the device's connection to the IP channel. Make sure that the firewall settings allow the device to communicate with the IP channel, you can try to turn off the firewall or add the appropriate rules.
Check the DNS settings: DNS resolution is an important part of connecting the device to the IP channel. Make sure that the DNS settings of the device are correct, you can try to use a different reliable DNS server or manually configure the DNS server address.
Check the configuration of network devices: If the devices are connected to network devices such as switches or routers, make sure that the devices are correctly configured, including VLAN settings and port configurations.
Check the service provider settings: If you use the IP channel service of a third-party service provider, make sure that the relevant settings are correct, including the account, password, and server address.
