Self-hosting in VM does not work

[kidaufo]

I'm trying to self-host langfuse v3 in a VM (EC2 instance) using docker-compose, but I can't connect to http://:3000 from local browser. I could connect to http://localhost:3000 (which is a bit weird) but I can't log anything.

I found the document here, but I doesn't mention which file should be modified.

Could you please provide guidance on how to properly configure it?

Hey @kidaufo! I'm here to help you with any bugs or questions you have about Langfuse. Let's work together to resolve your self-hosting issue.

To resolve the issue with self-hosting Langfuse on your EC2 instance, follow these steps to configure your Docker Compose file:

1. Set HOSTNAME: Modify your Docker Compose file to include HOSTNAME=0.0.0.0 in the environment variables. This allows Langfuse to accept connections from any IP address. Here's an example:

   services:
     langfuse:
       environment:
         - HOSTNAME=0.0.0.0

2. Check NEXTAUTH_URL: Ensure the NEXTAUTH_URL environment variable is set to the URL you are using to access Langfuse, such as http://<instance-ip>:3000. Update your Docker Compose file accordingly:

   services:
     langfuse:
       environment:
         - NEXTAUTH_URL=http://<instance-ip>:3000

3. Port Exposure: Make sure port 3000 is correctly exposed in your Docker Compose file:

   services:
     langfuse:
       ports:
         - "3000:3000"

4. Security Group Settings: Ensure your EC2 instance's security group allows inbound traffic on port 3000. You need to add a rule to the security group to permit traffic on this port.

By making these adjustments, you should be able to access Langfuse at http://<instance-ip>:3000 from your local browser ^[1][2].
