[TYPO3-english] Reverse proxy breaks backend URLs

[Mark Boland]

Hi Glenn,

try to use your external URL as Server Name and your internal as one of your Server Aliases in your web server’s config (not easy to accomplish with server_name in Nginx). I don’t know exactly how the URLs of various parts and extensions in the backend are constructed, but by using this setting, scripts that prepend the HOST_NAME to build their URLs will simply add the default name.

In Nginx, the HOST_NAME will automatically be built from the request (which will be your internal one). You may have to rewrite the requests, then.

Cheers,
Mark

    Hi,
    
    I'm running TYPO3 7.6 behind a reverse proxy (nginx proxy_pass).
    
    I've figured out that I needed out to add a domain record to my site to make it display.
    
    However, lots of image links in the backend are broken. These URLs point to the internal hostname of the machine that TYPO3 is installed on (which is not visible to the internet) rather than the external domain name that the user types into the browser.
    
    Examples of what is broken include dotted lines in the backend page module and images in the rich text editor.
    
    I made a Stack Overflow post about this a while ago, but haven't got a (complete) answer. I'm not allowed to link to the post because of this forum's spam protection, but the title is "how-do-i-tell-typo3-what-its-url-is-when-using-a-reverse-proxy".
    
    Any help would be much appreciated.
