First, make sure that the device is connected to the Internet and can access the URL you are trying to access. You can try to open the URL directly in the browser to test; 2. Check the URL to ensure that the URL you are trying to access is is correct and so on.

"Failed to fetch" error usually occurs when the network request fails. It may be caused by various reasons, including but not limited to: Network connection issues , URL error, server error, software or library version incompatibility, etc. Here are some common solutions:

1. Check the network connection: First, make sure your device is connected to the Internet and can access the URL you are trying to access. You can try opening that URL directly in your browser to test it. If the network connection is unstable or slow, a "Failed to fetch" error may occur. In this case, try waiting for some time and try again.

2. Check the URL: Make sure the URL you are trying to access is correct. If you are trying to access a dynamically generated URL, make sure it actually exists at that point in time. You can enter the URL directly into your browser to check if it is valid.

3. Check the server status: If the URL is correct and your device can access the Internet, it may be a server-side problem. You can try accessing the same URL in your browser and see if you get the correct response. If the server returns an error status code (such as 404 or 500), then you need to handle it according to the specific situation. For example, if the server returns a 500 error, you may want to display a friendly error message to the user rather than crash directly.

4. Handling exceptions: In your code, you should write code to handle exceptions if the network request fails. This means you should consider how your program should respond if the request fails. For example, you might want to print an error message when a request fails, or retry the request.

5. Update software and libraries: If your code uses a library or tool to send network requests, make sure you are using the latest version. Sometimes there may be known issues or incompatibilities with older versions of libraries or tools, and updating to the latest version may resolve your issue.

6. Use cache: In some cases, the server may not be able to respond to requests normally due to excessive load or other reasons. In this case, you can consider using cache to store previously obtained data to reduce request pressure on the server. When a request fails, you can try to get the data from the cache.

7. Use breakpoints and logs: If you still can't solve the problem, consider adding breakpoints or logging to your code to better understand the problem. You can view the execution path of the code, the values ​​of variables, etc. to help diagnose problems.

8. Seek professional help: If you have tried the above methods and still cannot solve the problem, you may need to seek professional technical support or consult professionals for help.

Remember, "Failed to fetch" errors can have many causes, and you need to carefully examine your code and environment to find out the specific cause. Each situation may require a different solution, so you'll need to choose the most appropriate solution based on your specific situation.
