@RaviRa1 

What is the submit action you're using- Is it REST? I wanted to check why you are posting the data to another form. It should ideally be a servlet call.

Did you try to change the hostname to FQDN instead of localhost?

I see the below-mentioned error msg for the submission. 

Couldn't post data to http://127.0.0.1:4506/content/forms/af/dataTestForm for form /content/forms/af/test-adpative-form-2408/jcr:content/guideContainer

Yes its coming when I am using submit action provided in forms. 

I have replaces http://localhost to 127.0.0.1 the path where i wan to post in the form. Still this issue is there.

No client side customization is done on the form
