Could not resolve host: ghtchina.com; Unknown error-Go服务器开发

The error message “Could not resolve host: ghtchina.com” typically indicates that your system is unable to find the specified hostname. Here are some troubleshooting steps you can take to resolve this issue:

1. Check Internet Connection

Make sure that you have a working internet connection. You can try pinging a well-known website, such as Google, to confirm:

ping google.com

2. Check Hostname Spelling

Ensure that the hostname ghtchina.com is spelled correctly in your command.

3. DNS Configuration

Your computer may have issues with its DNS configuration:

Try using Google’s public DNS by updating /etc/resolv.conf (on Linux) or through your network settings.

# Example for /etc/resolv.conf (Linux)
sudo nano /etc/resolv.conf

# Add the following lines if they don't exist:
nameserver 8.8.8.8
nameserver 8.8.4.4

# Save and exit

4. Flush DNS Cache

If you’re on macOS or Windows, flushing the DNS cache might help:

Windows: Open Command Prompt and run:
```
ipconfig /flushdns
```
macOS: Open Terminal and run:
```
sudo killall -HUP mDNSResponder
```

5. Test with Another Network or Device

If possible, try accessing the URL from another network (like a mobile hotspot) or device to determine if it’s an issue with your current network.

6. Verify GitLab URL

Confirm whether ght.gitlab/5gc/udm.git is accessible via a web browser and whether there are any known outages for that service.

If you’ve tried these steps and are still having trouble, please provide more details about your environment (e.g., operating system, git version) for further assistance!
