Fixing Docker GHCR TLS Timeout Error

Fixing Docker GHCR TLS Timeout Error | Generated by AI

Home 2025.10

The error you’re encountering, Get "https://ghcr.io/v2/": net/http: TLS handshake timeout, typically indicates a network issue when Docker tries to pull images from GitHub Container Registry (GHCR). Here are some steps to troubleshoot and fix the issue:

1. Check Your Internet Connection

Ensure your machine has a stable internet connection.
Try accessing https://ghcr.io in your browser to confirm you can reach the site.

2. Check Docker Daemon Status

Restart the Docker daemon:
```
sudo systemctl restart docker
```
Verify Docker is running:
```
sudo systemctl status docker
```

3. Configure Docker DNS

If you’re behind a corporate network or proxy, Docker might need custom DNS settings.
Edit or create /etc/docker/daemon.json:
```
{
  "dns": ["8.8.8.8", "1.1.1.1"]
}
```
Restart Docker:
```
sudo systemctl restart docker
```

4. Check for Proxy Settings

If you’re behind a proxy, configure Docker to use it:

mkdir -p ~/.docker
echo '{
  "proxies": {
    "default": {
      "httpProxy": "http://your-proxy-address:port",
      "httpsProxy": "http://your-proxy-address:port",
      "noProxy": "localhost,127.0.0.1"
    }
  }
}' > ~/.docker/config.json

Replace your-proxy-address:port with your actual proxy details.

5. Retry Pulling the Image Manually

Try pulling the image manually to see if the issue persists:
```
docker pull ghcr.io/librechat/librechat:latest
```
If it works, retry docker-compose up -d.

6. Check for Firewall/Network Restrictions

Ensure your firewall or network isn’t blocking access to ghcr.io.
Temporarily disable the firewall to test:
```
sudo ufw disable
```
(Re-enable it after testing if needed.)

7. Update Docker and Docker-Compose

Ensure you’re using the latest versions:

sudo apt update && sudo apt upgrade docker-ce docker-compose-plugin

8. Set UID/GID Environment Variables

The warnings about UID and GID are not critical, but you can set them in your .env file or docker-compose.yml to suppress the warnings:
```
echo "UID=$(id -u)" >> .env
echo "GID=$(id -g)" >> .env
```

9. Use a Different Registry Mirror (Optional)

If GHCR is consistently unreachable, you can try using a mirror (though this is not recommended for production):
```
{
  "registry-mirrors": ["https://mirror.example.com"]
}
```
Add this to /etc/docker/daemon.json and restart Docker.

10. Check for Time Synchronization

Ensure your system time is synchronized:

sudo apt install ntp
sudo systemctl restart ntp

Summary Table of Commands

Step	Command/Action
Restart Docker	`sudo systemctl restart docker`
Check Docker Status	`sudo systemctl status docker`
Configure DNS	Edit `/etc/docker/daemon.json`
Pull Image Manually	`docker pull ghcr.io/librechat/librechat:latest`
Set UID/GID	`echo "UID=$(id -u)" >> .env`

If the issue persists after trying these steps, let me know the output of:

docker info

and any error messages you see when running the above commands. This will help diagnose further!
