In that case, you can wait for a few minutes and try again. If the error persists, then you need to reach out to your web hosting provider’s support team.

Cloud or VPS Server Connectivity Issue

If you are on a cloud server or VPS hosting, then it is possible that your server is unable to connect to due to some DNS issues.

In that case, you can point your server directly to servers. You will need to connect to your server using SSH.

SSH is short for secure shell which is an encrypted protocol that allows you to connect to your server using command line tools.

Windows users can use a tool called PuTTy whereas macOS and Linux users can use the terminal app.

You will need login credentials for the account with shell access to your hosting account. You can get this information from your hosting account’s cPanel dashboard or ask your web hosting server provider.

In the terminal, you can connect to your server like this:


Don’t forget to replace ‘username’ with your own username and ‘’ with your own domain name.

Once connected, you need to run the following command:

sudo nano /etc/hosts

You can now save your changes and exit the editor. Visit your WordPress website to see if this has resolved the error.

If you are running WordPress on your own computer (localhost), then you may not have the cURL extension enabled for PHP. This extension is required to access for updates.

You will need to edit the php.ini file on your computer. This file is usually located in the PHP folder of your MAMP, XAMPP, or WAMP folder.

Lastly, don’t forget to restart the Apache server for changes to take effect.

Check Open Ports in Your Firewall

If the cURL extension is properly installed on your local server, then the next step is to check your internet connection firewall.

Your computer’s firewall may be blocking outgoing connections from the local server to If you are on Windows, then press the Start button and search for ‘Windows Firewall’. Mac users can find firewall settings in System Settings » Network » Firewall.

      If the method in this guide does not work for you, we would recommend reaching out to your hosting provider to ensure there are no errors on their end.

    I actually had to remove the ‘’ from /etc/hosts/ to make it work (it must have been there from an old wordpress project)

  4. Jon Curtis says

    Another reason one can get this error is when WP_HTTP_BLOCK_EXTERNAL is set in wp-config.

    I had set this in order to work on a local server while offline, and needed to stop WP from timing out and slowing the site down. But then forgot to turn it back on when I got back online.

    • WPBeginner Support says

      Thanks for sharing that for those who may have added this and are looking for other reasons for this error.

    Sir, in my php.ini there is no file as “;extension=php_curl.dll or extension=php_curl.dll” what should I do?

      You would want to ensure php_curl is installed and if it is, you would want to try the other recommendations in the article
