Title: haproxy problem accessing wp-admin Last modified: December 4, 2025 --- # haproxy problem accessing wp-admin * Resolved [cshabazian](https://wordpress.org/support/users/cshabazian/) * (@cshabazian) * [4 months ago](https://wordpress.org/support/topic/haproxy-problem-accessing-wp-admin/) * I am using an external IP address via _[ redundant link deleted ]_ which directs traffic to a server I’m running haproxy on. This works just fine to access the wordpress site landing page (main page) via public URL FQDN (Example: `https:// wp.mywordpress.com`), but any other pages it redirects it to the site/home URL which is the internal IP address of the site (Example: `http://192.168.1.1`). This works fine for me on my home network of course, but I cannot access anything via the public URL. If I change the site/home URL to the external FQDN, then it stops working. There is obviously a setting I need somewhere in WordPress, but I’ve tried using a rewrite with .htaccess, setting the home/site URL to the external address, and it doesn’t work. Help or pointers would be very much appreciated! My haproxy setup is very simple:`########################## FRONTENDS ########################## frontend webservers    bind :80    bind *:443  ssl crt /etc/letsencrypt/live/ mywordpress.com/fullcert.pem    redirect scheme https code 301 if !{ ssl_fc } mode http# wp.mywordpress.comacl host_wp.mywordpress.com hdr(host) -i wp.mywordpress. comuse_backend wp.mywordpress.com if host_wp.mywordpress.com########################## BACKENDS ############################ wp.mywordpress.combackend wp.mywordpress. comserver wp.mywordpress.com 192.168.1.1:80 check(NOTE: The SSL termination on the haproxy works just fine.

Try these: 1. Go to wp-config.php and add: define(‘WP_HOME’, ‘[https://wp.mywordpress.com’](https://wp.mywordpress.com’);); define(‘WP_SITEURL’, ‘[https://wp.mywordpress.com’](https://wp.mywordpress.com’);); 2. Or via database: Update wp_options table: siteurl = [https://wp.mywordpress.com](https://wp.mywordpress.com) home = [https://wp.mywordpress.com](https://wp.mywordpress.com) 3. Make sure haproxy is forwarding the Host header correctly. Add to haproxy: reqadd X-Forwarded-Proto: httpsreqadd X-Forwarded-Host: wp.mywordpress.com * This tells WordPress the external URL when accessed through the proxy. Give these a try! * Thread Starter [cshabazian](https://wordpress.org/support/users/cshabazian/) * (@cshabazian) * [4 months ago](https://wordpress.org/support/topic/haproxy-problem-accessing-wp-admin/#post-18741831) * Thanks for the advice. I changed the backend to: * ```wp-block-code backend wp.mywordpress.comhttp-request add-header X-Forwarded-Proto httpshttp-request add-header X-Forwarded-Host: wp.mywordpress.comserver wp.mywordpress.com 192.168.1.1:80 check ``` * And configured the site/home url to [https://wp.mywordpress.com](https://wp.mywordpress.com) but I’m getting too many redirects: ===================================== * This page isn’t working * **wp.mywordpress.com** redirected you too many times. * ===================================== * FYI, it DOES now work properly for other links. Example, I click on an entry, and it takes me to it instead of the internal IP address page, so it just seems to be a problem with wp-admin now - This reply was modified 4 months ago by [cshabazian](https://wordpress.org/support/users/cshabazian/). - This reply was modified 4 months ago by [cshabazian](https://wordpress.org/support/users/cshabazian/). - This reply was modified 4 months ago by [cshabazian](https://wordpress.org/support/users/cshabazian/). - This reply was modified 4 months ago by [cshabazian](https://wordpress.org/support/users/cshabazian/). * Thread Starter [cshabazian](https://wordpress.org/support/users/cshabazian/) * (@cshabazian) * [4 months ago](https://wordpress.org/support/topic/haproxy-problem-accessing-wp-admin/#post-18743194) * Just to be clear (because I received a moderator message telling me to post in the correct forum), I am using SELF HOSTED WordPress.org. I assume I got that email because of the “representative URL” I have above. I will change it from. com to .org in future posts to clarify. - This reply was modified 4 months ago by [cshabazian](https://wordpress.org/support/users/cshabazian/). * Thread Starter [cshabazian](https://wordpress.org/support/users/cshabazian/) * (@cshabazian) * [4 months ago](https://wordpress.org/support/topic/haproxy-problem-accessing-wp-admin/#post-18743272) * Ok, so for anyone who runs across this in the future, the problem was due to the fact that I am terminating SSL on the proxy, and my backend is on port 80. The fix is to add the following (I put it before Database settings, but you should be able to put it anywhere) * ```wp-block-code // ** This is because the front end is https and the back end is http ** //$_SERVER['HTTPS'] = 'on'; ``` Viewing 4 replies - 1 through 4 (of 4 total) You must be [logged in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fhaproxy-problem-accessing-wp-admin%2F%3Foutput_format%3Dmd&locale=en_US) to reply to this topic. * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 4 replies * 3 participants * Last reply from: [cshabazian](https://wordpress.org/support/users/cshabazian/) * Last activity: [4 months ago](https://wordpress.org/support/topic/haproxy-problem-accessing-wp-admin/#post-18743272) * Status: resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
