Solving ‘NetworkError when attempting to fetch resource’ in JavaScript
When making network requests in JavaScript, you may encounter the ‘NetworkError when attempting to fetch resource’ error. This error typically occurs due to various reasons, such as:
- Invalid or unreachable endpoint: Ensure that the URL you are fetching the resource from is correct and the server is accessible.
- Cross-Origin Request (CORS): The server hosting the resource may have CORS restrictions preventing your JavaScript code from accessing it. Ensure that the server allows cross-origin requests.
- Blocked by firewall or antivirus: Check if your firewall or antivirus software is blocking the connection to the server.
- Network connectivity issues: Ensure that your device has a stable internet connection and is not experiencing any network issues.
- Resource not available: The resource you are trying to fetch may not be available temporarily or permanently.
To solve this error, follow these steps:
- Verify the Endpoint: Double-check the URL of the endpoint you are attempting to fetch the resource from. Make sure it is correct and the server is running.
- Configure CORS: If the issue is related to CORS, you can configure the server to allow cross-origin requests by setting appropriate headers in the response.
- Check Firewall and Antivirus: Disable your firewall or antivirus temporarily to test if they are causing the issue. If the error disappears, check their settings and add exceptions for the necessary connections.
- Troubleshoot Network Issues: Run network diagnostics on your device to ensure proper connectivity and rule out any network-related problems.
- Check Resource Availability: Ensure that the resource you are trying to fetch is available. Contact the server if necessary to verify its status.
By following these steps, you can identify and resolve the ‘NetworkError when attempting to fetch resource’ error and ensure successful retrieval of the resource in your JavaScript application.
yo, this iss good stufff
thi is useless. I’m disappointed
I’ve already tried the first two solutions on another website, but they didn’t work for me. I’ll try the third solution and let you know if it works
You should have explained the third solution better. It’s not clear to me how to implement it
Who wrote this article? A five-year-old? The grammar and spelling are atrocious
This article is nothing new. I’ve known about these solutions for years
Lol, who would have thought that the solution was so simple? I feel like an idiot for not figuring it out myself

This is the worst article I’ve ever read. It’s full of useless information and the writing is terrible
I’ve been trying to solve this problem for weeks. Thanks to this article, I finally found the solution
I’m not sure I understand the third solution. Can someone explain it to me in simpler terms?
