Laravel’s “cURL error 28 – Failed to connect to”

The “cURL error 28 – Failed to connect to” error in Laravel often means that the app is having trouble connecting to an external resource or API when attempting to make a cURL request to it. An issue with a “Connection timed out” is expressly mentioned in the error code 28.

Fixing Laravel’s “cURL error 28 – Failed to connect to” Issue

We can follow the below steps to fix the “cURL error 28 – Failed to connect to” error:

1. Firstly, check to see if the URL we’re attempting to access is valid and formatted correctly. Verify that the URL is free of typos and mistakes.

2. Also, make sure that the server has reliable network access to the desired resource. Look for any firewall restrictions, network guidelines, or other elements that might prevent outgoing requests.

3. Then, make sure the proper configurations are in place to permit cURL requests if the server is protected by a firewall or employs a proxy server.

4. We must also verify that DNS resolution is functioning properly. The right IP address should be found when the destination domain name is resolved.

5. Also, make sure that the SSL/TLS certificates are current and trusted by the server if the resource may be accessed through HTTPS. Verify the correct setup and certificate expiration.

6. Then, examine the settings for the cURL request timeout. It’s possible that we need to change the timeout settings if the resource is taking too long to respond.

7. In order to build retry logic for the cURL request, think about it. Retrying the request after a brief delay can also occasionally help mitigate transient network problems.

8. Make sure we’re running the most recent version of cURL. Because compatibility problems could exist with outdated cURL versions.

9. For more specific error messages or context regarding the cURL request, check the logs of the application.

10. Check to see if the server is in excellent health. Heavy server usage, resource depletion, or other problems may also impact network connectivity.

11. Check to see if our own APIs or services are operational if we’re sending requests to them. Check for any reported outages or the status of any third-party APIs before making a request.

12. Use a program like curl in the terminal to try making the same cURL request. This can assist in figuring out whether the problem is particular to the Laravel application.

13. If the problem persists, try submitting the identical request once more using several tools or libraries to determine whether the issue is consistent.

14. There can be networking or security group setups that must change if the Laravel app is on a cloud provider like AWS or Azure.

15. The problem sometimes arises due to network outages. Lastly, see whether the problem goes away after some time passes.
