Hi @keen stag. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
#i am accessing my app with IP address in nextjs14

This error is related to the security measures implemented in Next.js for Server Actions. As per the Next.js documentation (https://nextjs.org/docs/app/building-your-application/data-fetching/server-actions-and-mutations#allowed-origins-advanced), Server Actions compare the Origin header to the Host header (or X-Forwarded-Host). If these don't match, the request will be aborted. This is to ensure that Server Actions can only be invoked on the same host as the page that hosts it.
In your case, the x-forwarded-host header value localhost:3000 does not match the origin header value 192.168.18.71:3000, hence the error.
To resolve this issue, you can specify a list of safe origins using the serverActions.allowedOrigins option in your next.config.js file. This is particularly useful for applications that use reverse proxies or have a multi-layered backend architecture.
Here's an example of how to do this:
/** @type {import('next').NextConfig} */
module.exports = {
experimental: {
serverActions: {
allowedOrigins: ['192.168.18.71:3000'],
},
},
}
In the above code, replace '192.168.18.71:3000' with your actual IP address and port. This will allow Server Actions to be invoked from this origin.

@raven sand i don't want to hard code the IP address

Let me check the knowledge base for you. One moment! :books:
If you don't want to hardcode the IP address, you can use environment variables to set the allowed origins. You can define these variables in your .env.local file and then access them in your next.config.js file.
Here's an example of how to do this:
In your .env.local file:
ALLOWED_ORIGIN=192.168.18.71:3000
In your next.config.js file:
/** @type {{import('next').NextConfig}} */
module.exports = {
experimental: {
serverActions: {
allowedOrigins: [process.env.ALLOWED_ORIGIN],
},
},
}
In the above code, replace '192.168.18.71:3000' with your actual IP address and port. This will allow Server Actions to be invoked from this origin.
Remember to restart your Next.js server after making these changes for them to take effect.
For more information on how to use environment variables in Next.js, you can refer to the Next.js documentation on Environment Variables (https://nextjs.org/docs/app/building-your-application/configuring/environment-variables#loading-environment-variables).

@raven sand i don't want to add the IP address every-time i am accessing my app from IP address.

Let me check the knowledge base for you. One moment! :books:
If you want to allow any IP address to access your application without having to specify it each time, you might need to reconsider this approach due to security reasons. Allowing any IP address to access your server actions can expose your application to potential security threats.
However, if you still want to proceed, you might need to modify your server configuration or use a middleware to dynamically set the X-Forwarded-Host header to match the origin header. This is not directly related to Next.js and would depend on your server setup or hosting platform.
Please note that this approach is not recommended and can potentially expose your application to security risks. Always ensure to follow best security practices when configuring your application.
