Providers disappear after adding on Ubuntu 24.04, CCM 0.6.3

[Taimoor-Kamran]

Description:
On Ubuntu 24.04, whenever I add a provider (OpenAI or Gemini) in Claude Code Mux 0.6.3 and refresh the page, the provider disappears.

Installation method used:
Installed via pre-built binaries:

Download and extract (glibc version)

curl -L https://github.com/9j/claude-code-mux/releases/latest/download/ccm-linux-x86_64.tar.gz | tar xz

Move binary to PATH

sudo mv ccm /usr/local/bin/

Verify installation

ccm --version

Steps tried to fix the issue:

Deleted the config folder:

rm -rf ~/.claude-code-mux

Recreated it with full permissions:

mkdir -p ~/.claude-code-mux
chmod -R 777 ~/.claude-code-mux

Started CCM and added a provider → saved to server.

Problem:

Provider disappears after refreshing the page.

Config folder exists with correct permissions:

ls -la ~/.claude-code-mux

Output:

total 12
drwxrwxrwx 2 taimoor taimoor 4096 Nov 25 06:26 .
drwxr-x--- 24 taimoor taimoor 4096 Nov 25 06:28 ..
-rw-r--r-- 1 taimoor taimoor 1483 Nov 25 06:24 config.toml

Expected behavior:

Providers should remain saved permanently after refreshing the page.

Environment:

OS: Ubuntu 24.04

CCM version: 0.6.3

Using: OpenAI or Gemini API key

Request:
Please advise if this is a bug in the Linux build or if there’s a fix for persistent provider saving.

I ran into the same problem. I was able to add a provider (OpenRouter) via the web interface (it will still be there when I reload the page). But when I try to add a model, the frontend will claim "Model added and auto-saved", but when I reload http://localhost:13456/?tab=models it will say "No models configured".

I am running Linux Mint 22.2 and installed CCM version 0.6.3 via cargo, so this does not only affect the pre-built binary.
