Steps to reproduce

I used docker to deploy dify on the linux server 1.1.1.1 and wanted to access dify from my windows desktop by visiting the http://1.1.1.1:80 page
docker-compose up -d
docker-compose ps
All up
BUT I can not open the page
telnet 1.1.1.1 80 also failed

✔️ Expected Behavior

❌ Actual Behavior

BUT I can not open the page

To address the issue of not being able to access your Dify instance on port 80, follow these targeted steps:

1. Ensure Network Accessibility: Confirm that both your Windows firewall and any network security settings allow traffic on port 80 to your Linux server's IP address. If you're using a cloud-hosted server, also check the cloud provider's firewall or security group settings.

2. Check Docker Port Mapping: Verify that the Docker container serving Dify (likely an Nginx container) is correctly mapping its internal port 80 to the host's port 80. This can be confirmed through the docker-compose ps output, which should list a mapping like 0.0.0.0:80->80/tcp.

3. Validate IP Address and Connectivity: Make sure the IP address 1.1.1.1 is correctly assigned to your server and is reachable from your Windows desktop. Testing connectivity with a ping or accessing another service on a different port can help verify this.

4. Inspect Container Logs: Look into the logs of your Dify containers, especially the Nginx container, for any errors or warnings that might indicate why the connection is failing. Use docker logs <container_name> to view these logs.

5. Review Docker Network Settings: Ensure there are no Docker network configurations that might be restricting access to the containers.

6. Temporarily Disable Windows Firewall: As a test, disable the Windows Defender Firewall to see if it's blocking access. If access is restored, you'll need to add a rule to allow traffic on port 80.

7. Access via Localhost: If the Docker containers are running on your Windows machine, try accessing Dify via http://localhost or http://127.0.0.1.

8. Restart Docker Containers: Sometimes, a simple restart of the Docker containers can resolve connectivity issues. Use docker-compose down and then docker-compose up -d to restart.

If these steps do not resolve your issue, it may be necessary to delve deeper into your network configuration or seek specific advice based on your setup. Additionally, check the Dify self-hosted installation guide and the installation FAQ for any known issues with version 0.4.0 that might be relevant to your situation.

@dosu I use other linx server 2.2.2.2 to telnet 1.1.1.1 22 ,which can connected to 1.1.1.1,however when i telnet 1.1.1.1 80,which still failed and the log is "No route to host".What's more,i telnet 1.1.1.1 22 in linux server 1.1.1.1 ,which is succeed.

@dosu i telnet 1.1.1.1 80 in linux server 1.1.1.1 ,which is succeed.

I think you should access it using 1.1.1.1 instead of 1.1.1.1:80
