This error can be a headache, but don’t worry – I’ll guide you through understanding and resolving it, so your site can get back to running smoothly.
Understanding Curl Error 28
What on Earth is Curl Error 28?
Curl Error 28 is a timeout error that occurs when your WordPress site tries to communicate with remote servers. This error can be caused by various factors, such as server issues, plugin conflicts, and even security settings. Before we dive into fixing this error, let’s first understand what might be causing it.
Identifying the Culprit
Your WordPress site could be experiencing Curl Error 28 due to several reasons, like outdated software, incorrect timeout settings, or DNS issues. It can also happen if there’s a conflict between your plugins or theme, or if your site’s firewall or security settings are blocking communication.
Diagnosing Curl Error 28
Error Logs to the Rescue
When trying to diagnose Curl Error 28, your site’s error logs are your best friend. They’ll help you pinpoint what’s causing the issue. To access these logs, you can either check your server’s control panel or use a file manager to locate the
error_log file in your WordPress root directory. Once you’ve got the logs, look for entries that mention Curl Error 28.
Another method to diagnose Curl Error 28 is to check your server’s connectivity to remote servers. You can do this by running a simple command-line test. If the connection is blocked or slow, it might be the reason behind the error.
Resolving Server Issues
Update Your Curl and PHP
One common cause of Curl Error 28 is outdated Curl or PHP versions on your server. Make sure you’re running the latest versions, as they often include important bug fixes and security updates. To update, you can follow your hosting provider’s guidelines or contact their support team for assistance.
Timeout Settings Tweaks
Curl Error 28 can also be caused by low timeout settings. If your server takes too long to communicate with remote servers, it might time out and trigger the error. To fix this, try increasing the timeout duration in your
Sometimes, Curl Error 28 can be caused by improper DNS configuration. Double-check your server’s DNS settings, and if necessary, update them to use a reliable DNS provider like Google’s public DNS.
Resolving Plugin and Theme Conflicts
Finding the Troublemaker
Plugin conflicts are another common cause of Curl Error 28. To identify the problematic plugin, you can deactivate all plugins and reactivate them one by one, checking for the error each time. Once you’ve found the plugin causing the issue, you can move on to the next step.
Update or Replace Plugins
If you’ve found the plugin causing Curl Error 28, try updating it to the latest version, as this might resolve the issue. If updating doesn’t help, consider looking for an alternative plugin that provides similar functionality without causing the error.
Themes can also cause Curl Error 28, especially if they include custom functionality that relies on remote server communication. If you suspect your theme is causing the error, try switching to a default WordPress theme temporarily. If the error disappears, you’ll know it’s time to update or replace your current theme.
Firewall and Security Settings
Your server’s firewall settings could be preventing communication with remote servers and causing Curl Erro
To resolve this, review your firewall settings and make the necessary adjustments to allow your site to communicate with remote servers. If you’re not sure how to do this, reach out to your hosting provider’s support team for help.
Security Plugins: Friend or Foe?
While security plugins are essential for protecting your site, they can sometimes be the reason behind Curl Error 28. Review your security plugin’s settings and look for any options that might be blocking remote server communication. Adjust these settings as needed to resolve the error, or consider switching to another security plugin that doesn’t cause issues.
Working with Hosting Providers
Collaborating with Support Teams
Your hosting provider’s support team can be an invaluable resource when dealing with Curl Error 28. Don’t hesitate to contact them if you need assistance with diagnosing or resolving the issue. They’ll likely have access to more information and tools than you do, and they can help you get your site back on track.
Considering Alternative Hosting Solutions

When selecting plugins and themes for your site, opt for well-supported and reliable options. This can help you avoid conflicts and issues that lead to Curl Error 28. Check user reviews and ratings, and look for plugins and themes with a proven track record of compatibility and support.
FAQ on curl error 28
What is curl error 28?
Oh, that one! Curl error 28 is a timeout issue that you might encounter while using the cURL command-line tool or library. It basically means that the requested operation didn’t complete within the time frame you specified. It’s a bummer, but at least you know what’s up now, right?
Why does it happen?
Well, several things can cause curl error 28. One of the most common reasons is a slow server response. You know, when the server is taking its sweet time to respond. Other reasons could be network congestion, poor internet connection, or a hiccup in the DNS resolution. It’s all about the timing!
How do I fix it?
If you want to give it a go, start by increasing the timeout value. You can do that by adding the
--max-time options when using cURL. You might also want to check your internet connection, just to be sure it’s working properly. And if nothing seems to work, you could always try reaching out to the server admin to see if there’s an issue on their end.
Is there a way to avoid it in the first place?
To be honest, it’s pretty hard to completely avoid it. However, you can minimize the risk by making sure your server responds quickly and your internet connection is stable. And when using cURL, always set appropriate timeout values to avoid getting stuck waiting for a response that might never come.
What’s the difference between –connect-timeout and –max-time?
Ah, great question! So,
--connect-timeout sets the maximum time (in seconds) for the connection phase to complete. On the other hand,
--max-time limits the total time for the entire operation, including the connection phase and data transfer. Choose wisely, my friend!
How do I set a custom timeout value in PHP?
In PHP, you can easily set a custom timeout value when using the cURL library. Just use the
CURLOPT_TIMEOUT options with
curl_setopt(). You’ll be good to go in no time!
Can it be caused by a firewall?
It’s possible, but not very likely. A firewall could potentially block or delay the connection, leading to a timeout error. But if you’re able to access other websites, then your firewall is probably not the issue. You might want to investigate further.
What if increasing the timeout doesn’t help?
If increasing the timeout doesn’t make a difference, there might be an issue with the server itself. It could be overloaded or experiencing technical problems. In this case, you might want to contact the server admin to see if they can shed some light on the issue.
Is curl error 28 related to any specific operating systems?
Nope! Curl error 28 can happen on any operating system that supports the cURL tool or library. It doesn’t discriminate, and neither should you!
Is there any alternative to cURL that might not have this issue?
Well, you can try other tools like
wget or programming libraries like Python’s
requests. However, keep in mind that timeout issues can happen with any tool or library that relies on network connections. So it’s not a cURL-exclusive problem, but it’s always good to have options, right?
