Why Is My Domain Name or IP Address Inaccessible?

Symptoms

If Access Progress for a website you have added to WAF is Accessible, the connection between WAF and the website domain name or IP address has been established.

WAF automatically checks the access status of protected websites every hour. If WAF detects that a protected website has received 20 access requests within 5 minutes, it considers that the website has been successfully connected to WAF.

Troubleshooting and Solutions for WAF Instances

Refer to Figure 1 and Table 1 to fix connection failures.

Possible Cause

Solution

Cause 1: Access Status for Domain Name/IP Address not updated

In the Access Status column for the website, click to update the status.

Cause 2: Website access traffic not enough for WAF to consider the website accessible

NOTICE:

After you connect a website to WAF, the website is considered accessible only when WAF detects at least 20 requests to the website within 5 minutes.

  1. Access the protected website many times within 1 minute.
  2. In the Access Status column for the website, click to update the status.

Cause 3: Incorrect domain name or IP address settings

Check domain name or IP address settings.

If there are incorrect settings for the domain name or IP address, remove this domain name or IP address from WAF and add it to WAF again.

Cause 4: No load balancer configured for the dedicated WAF instance or no EIP bound to the load balancer configured for the dedicated WAF instance

  1. Configure a load balancer for dedicated WAF instances by referring to Configuring a Load Balancer.
  2. Bind an EIP to a Load Balancer.

Cause 5: Incorrect load balancer configured or incorrect EIP bound to the load balancer
