How can I access the ik-llama.cpp server from another computer?

[edyapd]

I'm trying to access the ik-llama.cpp server from another computer on my local network, but I'm running into an issue.

Setup:
The server is running on a machine with the IP address 192.168.0.110.
I started the server with the --host 0.0.0.0 flag to allow external connections.
The client machine is on the same network with the IP address 192.168.0.101.

Behavior:
When I access http://192.168.0.110:8080/ from a web browser on the same machine (the server machine), the web UI loads correctly. The server log shows a successful request:

INFO [      log_server_request] request | tid="5832" timestamp=1757425277 remote_addr="192.168.0.110" remote_port=59900 status=200 method="GET" path="/" params={}
INFO [      log_server_request] request | tid="5832" timestamp=1757425277 remote_addr="192.168.0.110" remote_port=59900 status=404 method="GET" path="/favicon.ico" params={}

However, when I try to access http://192.168.0.110:8080/ from the other computer, the browser receives a 404 error with this JSON response:

{"error":{"code":404,"message":"File Not Found","type":"not_found_error"}}

The server log for this failed remote request looks like this:

INFO [      log_server_request] request | tid="11080" timestamp=1757425238 remote_addr="192.168.0.101" remote_port=61851 status=404 method="GET" path="http://192.168.0.110:8080/" params={}
INFO [      log_server_request] request | tid="11080" timestamp=1757425239 remote_addr="192.168.0.101" remote_port=61851 status=404 method="GET" path="http://192.168.0.110:8080/favicon.ico" params={}

Could you please advise on how to properly configure the server for access from other computers on the network? Is this a known issue?

Thank you!

I typically use --port 5000 for the server, and then 192.168.0.110:5000 to connect the client

Thank you for your reply.
But unfortunately it doesn't work for me.
Client: Windows 7, Chrome.
I make a request to http://192.168.0.110:5000
In response I get:

{"error":{"code":404,"message":"File Not Found","type":"not_found_error"}}

Server: Windows 10
Message in console:

Remove --host 0.0.0.0 and add --port 5000 to your server command

[edyapd]

The server runs on a local address by default. I can't access it from another computer.

INFO [ main] HTTP server listening | tid="5128" timestamp=1757437264 hostname="127.0.0.1" port="5000" n_threads_http="31"

Client IP appears on the server logs, it means that firewall is not blocking the port.

You could try one of the API endpoints with curl to rule out browser issues, example:

curl -k http://192.168.0.110:8080/v1/chat/completions -H "Content-Type: application/json" -d '{ "model": "Qwen_Qwen3-30B-A3B-IQ4_KS.gguf", "messages": [ { "role": "user", "content": "Hello!" } ] }'

[edyapd]

Thanks for trying to help.
I don't have the curl command in Windows 7.
ChatGPT advised me to send it via the browser console:

fetch('http://192.168.0.110:5000/v1/chat/completions', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    model: 'deepseek-ai_DeepSeek-V3.1-IQ2_S-00001-of-00005.gguf.gguf',
    messages: [
      { role: 'user', content: 'Hello!' }
    ]
  })
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));

This is what I got in response:

 POST http://192.168.0.110:5000/v1/chat/completions 404 (Not Found)
 
{code: 404, message: 'File Not Found', type: 'not_found_error'}

And this is in the server console:

INFO [      log_server_request] request | tid="8300" timestamp=1757437884 remote_addr="192.168.0.101" remote_port=64968 status=404 method="GET" path="http://192.168.0.110:5000/" params={}
INFO [      log_server_request] request | tid="4728" timestamp=1757437938 remote_addr="192.168.0.101" remote_port=65130 status=404 method="POST" path="http://192.168.0.110:5000/v1/chat/completions" params={}

Hopefully is not IE 😄

Try with recent version of Firefox http://192.168.0.110:5000/v1/models, it should return a JSON in browser.

Thanks to everyone who responded. I figured out what the problem was. I’d spent two days asking ChatGPT about it and it couldn’t answer; today it got it right on the first try.

The issue was that the computer I was sending the request from had a proxy enabled. It was sending the full URL—instead of “/”, the server was receiving “http://192.168.0.110:8080/”, couldn’t handle it, and returned 404.

Sorry for taking up your time.
