Looks like there are too many other requests coming in with that POST.
Can you try increasing the number of requests logged as described here?
Maybe try setting it to 50 or 100 -- just remember to turn it back to 20 after you've grabbed the logs though.
Are you saying you can reproduce the issue by hitting AEM Publish directly via IP?
Do you have multiple AEM Publish instances? Are you sure the one you're getting Recent Requests for is the one you are hitting?
when am trying to access the API in publisher and Akamai url am getting the output with the success.
Whem am trying to perfrom operation in application for all the post calls am seeing the 204 issue.
Are you saying:
When you use a tool like Postman or CURL to hit the POST servlet via Akamai OR AEM Publish's IP, then the Servlet works.
When you invoke the action on your Web site that invokes the POST servlet, then you get the 204?
