WordPress behind HAProxy

[mr-elamin2]

Hi there,
I have a containerized WordPress server running multiple sites with Traefik, PHPMyAdmin, MySQL DB, and Redis for the cache.
I use only port 80 without SSL in the backend and everything works behind the Pfsense perfectly.
I use SSL Offloading in the HAProxy on my Pfsense but when I try to reach https://mysite.com/wp-admin the page never loads correctly and I can not send login data as well :(
please see the attached screenshots.
what shall I do on my firewall to make my sites work correctly from the Frontend?

login-to-view
login-to-view

I appreciate any answer :)
Thanks alot.

@mr-elamin2
Did you create a http to https redirect rule in the frontend?

[mr-elamin2]

@viragomann
Yes, all requests on port 80 will get redirected to port 443.
I have other sites and everything work fine except WordPress.!

Seems that the CSS cannot be fetched properly.

I don't use WP actually behind HAproxy, so I'm not experienced with it.
But you can use the debugging mode in the browser to find out, what's going wrong.

Hi all,

I have got the solution:

adding the bellow code to the wp-config.php file right after <?php in the file has solved my problem.

<?php

// force SSL
$_SERVER['HTTPS']='on';

define('WP_HOME','http://mysite.com');
define('WP_SITEURL','http://mysite.com');

Thanks all :)

Failed for me, but for WP 6.7.2, I added this to the top of the wp-config.php to make it work:

define('FORCE_SSL_ADMIN', false);
if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false)
$_SERVER['HTTPS']='on';

define('WP_HOME','http://sitename.com');
define('WP_SITEURL','http://sitename.com');
