Question

I want the web acl to be associated with the Application Load Balancer in the AWS region, after a few hours, I found that the association was cancelled, repeated many times with the same result, and in the Application Load Balancer configuration item integrated service (AWS WAF) shows: This Application Load Balancer does not support WAF, I don't know where the configuration is wrong，thank you

Answer

Hi, 
 
This could be because of the disassociation of the WEB-ACL.
look into cloud trial logs for disassociate-web-acl api call.
 
https://docs.aws.amazon.com/cli/latest/reference/wafv2/disassociate-web-acl.html  
 
Also, there are Restrictions on multiple association
 
You can associate a single web ACL with one or more AWS resources, according to the following
restrictions:
• You can associate each AWS resource with only one web ACL. The relationship between web ACL and
AWS resources is one-to-many.
• You can associate a web ACL with one or more CloudFront distributions. You cannot associate a web
ACL that you have associated with a CloudFront distribution with any other AWS resource type.

The web acl is associated with the Application Load Balancer in the AWS region. After a few hours, it is found that the association has been cancelled
