"Cross-site POST form submissions are forbidden" with ngrok in form actions

[alokmahor]

In my vite.config.js I have added

server: {
		allowedHosts: ['31a9-171-60-133-80.ngrok-free.app'], // Allow all ngrok subdomains
	},

But still I am getting Cross-site POST form submissions are forbidden

I tried setting ORIGIN in package.json also

"scripts": {
		"dev": "ORIGIN=https://31a9-171-60-133-80.ngrok-free.app vite dev",
}

None of the solution are working when I am trying to submit a form using actions. Without ngrok form submission is working fine.

How can make it work for development?
