Title: Problem setting up proxy server Last modified: October 18, 2019 --- # Problem setting up proxy server * [mooogle](https://wordpress.org/support/users/mooogle/) * (@mooogle) * [6 years, 5 months ago](https://wordpress.org/support/topic/problem-setting-up-proxy-server/) * I’m trying to set up WordPress on a server that requires a proxy connection to connect to the internet. Here’s what I put in wp-config.php: * ``` /* Configure HTTP Proxy Server */ define('WP_PROXY_HOST', 'xx.xx.xx.xx'); define('WP_PROXY_PORT', '8080'); define('WP_PROXY_USERNAME', 'xxxxx'); define('WP_PROXY_PASSWORD', 'xxxxx'); define('WP_PROXY_BYPASS_HOSTS', 'localhost'); ``` * (I replaced real IP, username and password with xxx here for privacy reasons) * Unfortunately, WordPress still can’t connect to the internet. The Site Health page displays this error: * `Your site is unable to reach WordPress.org at 198.143.164.251, and returned the error: cURL error 56: Received HTTP code 407 from proxy after CONNECT` * 407 is a Proxy Authentication Required error. * I checked the proxy’s IP, username and password many times, and it’s definitely correct. The same settings work when I use * `export http_proxy="http://xxxxx:xxxxx@xx.xx.xx.xx:8080"` * in the command line, and then download something using wget. It connects via proxy, and downloads the file correctly. * I tried using a packet capture program to see what the connection between WordPress and the proxy looks like, and the headers look like this: * ``` CONNECT api.wordpress.org:443 HTTP/1.1 Host: api.wordpress.org:443 User-Agent: WordPress/5.2.4; http://xx.xx.xx.xx/ Proxy-Connection: Keep-Alive Connection: close ``` * The reply from the proxy server is this: * ``` HTTP/1.1 407 authenticationrequired Date: Fri, 18 Oct 2019 11:31:00 GMT Content-Type: text/html Cache-Control: no-cache Content-Length: 4365 Proxy-Connection: Keep-Alive Proxy-Authenticate: Negotiate Proxy-Authenticate: NTLM Proxy-Authenticate: Basic realm="McAfee Web Gateway" ``` * I think that there should have been a * `Proxy-Authorization: Basic xxxxxxxxxxxxxxx` * header in the first packet, but for some reason there isn’t anything like it. What should I do? Am I missing something obvious here? - This topic was modified 6 years, 5 months ago by [mooogle](https://wordpress.org/support/users/mooogle/). - This topic was modified 6 years, 5 months ago by [mooogle](https://wordpress.org/support/users/mooogle/). - This topic was modified 6 years, 5 months ago by [mooogle](https://wordpress.org/support/users/mooogle/).

But the proxy is working well outside WordPress, only WordPress has a problem with it, so I think it’s unlikely that it’s a problem with the proxy’s configuration. * (I actually posted this on Stack Exchange too) * [autotutorial](https://wordpress.org/support/users/autotutorial/) * (@autotutorial) * [6 years, 5 months ago](https://wordpress.org/support/topic/problem-setting-up-proxy-server/#post-12043212) * You need to bypass host wordpress.org are you the owner of wordpress.org? If you are not, your proxy cannot connect to it (the destination server must be prepared for the proxy otherwise it will not work) Wildcards [https://techjourney.net/how-to-enable-use-proxy-server-for-wordpress-to-connect-internet/](https://techjourney.net/how-to-enable-use-proxy-server-for-wordpress-to-connect-internet/) * Thread Starter [mooogle](https://wordpress.org/support/users/mooogle/) * (@mooogle) * [6 years, 5 months ago](https://wordpress.org/support/topic/problem-setting-up-proxy-server/#post-12049032) * Hi! Thanks for the reply, I actually followed the instructions you’ve linked, but it’s not working. I’m not the owner of wordpress.org, my wordpress installation needs connection to wordpress.org to install plugins and updates. Internet connection works through proxy, but the proxy doesn’t seem to work on wordpress. * [jbunston](https://wordpress.org/support/users/jbunston/) * (@jbunston) * [6 years, 4 months ago](https://wordpress.org/support/topic/problem-setting-up-proxy-server/#post-12123494) * Having the same issue. We are actually using CNTLM proxy for linux, running on a Linux VM, which allows us to direct all proxy activity to the CNTLM instance running on port 3128. We do this to avoid needing to use credentials int he WordPress setup. * It’s failing for us too. Somthing changed in Wordress. The local linux instance it runs on has no issues poking through for OS updates. * [zfscgy](https://wordpress.org/support/users/zfscgy/) * (@zfscgy) * [6 years ago](https://wordpress.org/support/topic/problem-setting-up-proxy-server/#post-12625670) * I had the same problem. I set up a proxy on **localhost**, and all things worked fine except wordpress. **I cannot install plugins**. The error message shows Cannot build secure connection to wordpress.org(wp-admin/includes/install-plugins. php line:182) I guess the reason is that the plugin-installing site of wordpress. org is not allowed to visit by a proxy, since it may verify your address. And in the tutorial, you can see they added “*.wordpress.org” to the bypass list.
