One of the reasons you are getting this error message may be because your web server is badly configured, resulting in it being unable to WordPress.org.<\/li><li><strong>Your website is under strain because of heavy resources or traffic. <\/strong>Having a low resource space can be bad especially if your site is getting heavy traffic. If you\u2019re using shared hosting for your site, this could be your dilemma. Shared hosting comes with limited resource space, so if your site has a lot of traffic it can strain the web server\u2019s resources resulting in a secure connection error.<\/li><li><strong>Badly configured firewall. <\/strong>Firewalls are installed on websites to protect them from malicious attacks. The problem comes when these firewalls are badly configured; they become too protective. These firewalls may prevent you from performing changes like the installation or updating of plugins or themes in your WordPress website. They could block entire ports, disabling the ones needed by your website. All this can cause you to get a secure connection error in WordPress.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Fix_Secure_Connection_Error_in_WordPress\"><\/span>How to Fix Secure Connection Error in WordPress<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Check_if_your_web_server_is_under_a_DDoS_attack\"><\/span>Check if your web server is under a DDoS attack<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>If your web server is getting a secure connection error, there are chances that your website is under a DDoS attack. These can cause every connection you attempt to establish with WordPress.org to timeout, thus causing a secure connection error.<\/p>\n\n\n\n<p>The issue mostly gets resolved on its own, so give it a few minutes then retry the connection. If you cannot create a connection, \u200ccontact your web hosting provider for help.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Check_for_DNS_issues\"><\/span>Check for DNS issues<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>If your website is hosted on cloud or VPS, then it\u2019s possible the reason you are getting this secure connection error may be because of DNS issues. These can be the reason your web server cannot connect with WordPress.org.<\/p>\n\n\n\n<p>To fix this issue, connect to your web server using Secure Shell Access (SSH). SSH is an encrypted protocol that lets you get secure access to your web server and perform changes to your file using command-line tools.<\/p>\n\n\n\n<p>If you\u2019re using Windows, you will need a tool called <strong>PuTTy <\/strong>to gain this access. For Mac and Linux users, you can use the terminal app.<\/p>\n\n\n\n<p>Once you have installed PuTTy into your Windows, run the tool and select <strong>SSH <\/strong>as your <em>Connection Type<\/em>. In <em>Hostname<\/em> enter the address provided to you by your web host. Enter all the required login credentials, if you are sure of what to do, you can contact your web host for assistance.<\/p>\n\n\n\n<p>Once you\u2019re logged into the terminal, enter the following commands to connect the terminal to your server:<\/p>\n\n\n\n<p>ssh<\/p>\n\n\n\n<p>username@domain.com<\/p>\n\n\n\n<p>Replace the username and domain with your own username and domain name.&nbsp;<\/p>\n\n\n\n<p>Once you are connected, run the following command to go to the <em>Hosts <\/em>file:<\/p>\n\n\n\n<p>sudo nano \/etc\/hosts<\/p>\n\n\n\n<p>This allows you to access the <em>host&#8217;s <\/em>file using nano editor. Now add the following code to the bottom of the file.<\/p>\n\n\n\n<p>66.155.40.202 api.wordpress.org<\/p>\n\n\n\n<p>The aim of the code in the host file is to map WordPress.org to the correct IP address. When you are done, save the changes and exit. Go back to your website and check if the error has been resolved.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Check_if_the_cURL_Extension_is_Enabled_for_PHP\"><\/span>Check if the cURL Extension is Enabled for PHP<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>WordPress relies a lot on PHP for its functionality. This can be an issue if you don\u2019t have the right version installed. If you are hosting your WordPress website on your computer, there are chances \u200cyou don&#8217;t have the cURL extension enabled for PHP.<\/p>\n\n\n\n<p>The cURL extension is a PHP extension that allows your WordPress website to connect to WordPress.org to access updates. This extension is required for downloads or updates of plugins or themes from the official repository.<\/p>\n\n\n\n<p>You can find this file extension in the PHP folder of your WAMP, Mamp, or Xampp folder.<\/p>\n\n\n\n<p>Connect to your server using SSH, then enter the following command:<\/p>\n\n\n\n<p>sudo nano \/etc\/php.ini<\/p>\n\n\n\n<p>If you\u2019re using Windows, look for the following line of code within the file:<\/p>\n\n\n\n<p>;extension=php_curl.dll<\/p>\n\n\n\n<p>For Mac and Linux users, look for the following lines:<\/p>\n\n\n\n<p>;extension=curl.so<\/p>\n\n\n\n<p>If you can\u2019t find them, \u200cadd them. Don\u2019t forget to remove the semicolon, now save the changes to your php.ini file, and reload your server.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Check_if_the_right_ports_are_open_on_your_firewall\"><\/span>Check if the right ports are open on your firewall<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>If your cURL extension is properly installed, then the secure connection error is probably caused by your firewall blocking ports required for connection with WordPress.org.<\/p>\n\n\n\n<p>If there\u2019s a firewall installed on your web server, \u200ccheck to ensure it isn\u2019t blocking any of the necessary ports. You can also check if the firewall installed on your device is also blocking the connection.<\/p>\n\n\n\n<p>If you are using Windows, click on start and run a search for Windows Firewall. For Mac users, go to <strong>System Preference &gt; Security &amp; Privacy <\/strong>to configure your firewall.<\/p>\n\n\n\n<p>Add Apache to the list of programs that your firewall should allow for both incoming and outgoing connections.&nbsp;<\/p>\n\n\n\n<p>You can also contact your web host to check if the source of the secure connection error is from Firewall.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Does the message \u201cUnable to establish secure connection\u201d error keeps popping up on your screen whenever you
