WordPress – Error @ Server at Port 443

Port 443 is the standard port for all secured HTTP traffic, meaning it’s absolutely essential for most modern web activity. With regular HTTP over port 80, everything exchanged between your computer and a website is available for anyone to see in plain text.

Port 443 also enables websites to be available over both HTTP and HTTPS. Most websites are configured to work with HTTPS over port 443, but if it isn’t available for some reason, the website will still be live over HTTPS on port 80. In the past, not every web browser supported HTTPS, meaning it wasn’t universally accessible. Now, though, most major browsers are moving to mark websites that don’t offer HTTPS traffic as insecure.

Sometimes after installing an SSL certificate you might get a 443 error when navigating to another page of your website. But if you are hosting your own website and you get this error on all pages first make sure that port 443 is not being blocked by a firewall, in your router etc.. also make sure the port forwarding settings set it as open. Some ISP block this port so make sure that that they have this port open.


<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

If the port is open then it’s time to check some of your WordPress settings.

I like to fix this the easy way so you can start by installing a plugin called Really Simple SSL we have found that this will fix most problems. Sometimes just installing Really Simple SSL will not fix the problem, you will have to deactivate revert to HTTP, and reactivate. I have found that this will work 99% of the time.

If this does not work, using an explorer open the .htaccess file in the main directory, and copy and paste the code on the Left-hand side.
