Why Cannot I Access Public Websites Through Domain Names or Access Internal Domain Names in the Cloud When My ECS Has Multiple NICs?

When an ECS has more than one NIC, if different DNS server addresses are configured for the subnets used by the NICs, the ECS cannot access public websites or internal domain names in the cloud.

You can rectify this fault by configuring the same DNS server address for the subnets used by the same ECS. You can perform the following steps to modify DNS server addresses of subnets in a VPC:

  1. Log in to the management console.
  2. On the console homepage, under Network, click Virtual Private Cloud.
  3. In the navigation pane on the left, click Subnet.
  4. In the right pane displayed, view the DNS server addresses of each subnet.
  5. Click Modify in the right corner of each subnet and modify the DNS server address in the displayed dialog box.
  6. Click OK.
