Form feedback code: rest_no_route, with 404 status

I’m using Contact Form 7 and WP-Rocket Plugins. However, from last week, forms have not been submitted from the site and show the following error.

Responce{
ok: 
false
redirected
: 
true
status
: 
404
statusText
: ""
type
: 
"basic"
url
: 
"https://www.technource.com/wp-json/contact-form-7/v1/contact-forms/***/feedback/"
}

And Feedback
{
    "code": "rest_no_route",
    "message": "No route was found matching the URL and request method.",
    "data": {
        "status": 404
    }
}

When I disable the WP-Rocket Plugin, it works fine and all forms are getting submitted. But, when I enable the WP-Rocket Plugin, it again gives above mentioned error.

Takayuki Miyoshi Please suggest the best solution to resolve it.
