Kirby behind Nginx Reverse Proxy on separate hosts

I have a bunch of test apps up on my local network and recently got into kirby. I love the structure & design of this CMS and am planning on using it a lot. I am currently building my first website in kirby and would like to show progress with the client before moving to a licensed hosted solution.

My setup is as follows:

registered with my DNS to point to my public IP
-> router port forwarding 
-> public facing [Nginx Proxy Manager]( on a Raspberry Pi 4 , with SSL termination
-> virtual alpine linux server with php7.4+apache2+kirby3 serving the website on http

Now, I can access the kirby server on my local network under its hostname, but if I put in under "ServerName" in the /etc/apache/httpd.conf it breaks the system - I can netiher access it under its hostname nor through the internets under its public hostname.

I have other sites/apps accessible from the internets under the same domain, so I know the reverse proxy works & I have read the different posts here regarding nginx reverse proxy, but I havent figured out which of the settings need to be on the apache server with kirby and which need to be on the nginx reverse proxy.

I’ve tried setting some custom location settings and other things on the reverse proxy based on the different solutions proposed on the forum but I feel like I need some combination of editing the apache/httpd.conf and editing the nginx-proxy in front.

The error message I get seem to be related to the DNS strangely, “ERR_NAME_NOT_RESOLVED” so something weird is going on.

Anyone got experience with this?

If I understand correct, you have only one domain name pointing to your Proxy and multiple virtual hosts running behind the proxy. I wonder how you get manage to serve these multiple virtual hosts to the outer world?

I have a rather similar setup, but with Apache as Proxy as well. In the proxy the configuration directive ProxyPreserveHost On must be set in order to forward the requested virtual hostname to the backend server. Then you can have an unlimited number of domain names pointing to the proxy, and the proxy will forward the name when contacting the backend.

On the backend server I am running at least 2 virtual hosts for the same site, but with different virtual host settings, one is listening for connections from the local network, one for connections from the proxy. The ServerName directive however is exactly the same, since the site should be accessible by the same name regardless if the client is in the local network or outside (via the proxy).

I do not know if this helps you solving the problem, all I can tell you is that it is possible :wink:

To dig further into it, you will need to provide more information, i.e. the configuration files for the apache backend and the nginx proxy.

edit: I did some updates and now the configurations posted here work.

thanks for taking the time to try and figure this out with me c:

I have two domain names, both of them I have different microservices on different subdomains: for my nextcloud server for my media server, for a soon to be mattermost server
my.domain & are going to be for my partner and my kirby built home pages c:

Both of these are on with the appropriate @, cloud, media, etc, subdomains pointing to our home IP.

# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:> for detailed information.
# In particular, see 
# <URL:>
# for a discussion of each configuration directive.
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/access_log"
# with ServerRoot set to "/usr/local/apache2" will be interpreted by the
# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log" 
# will be interpreted as '/logs/access_log'.

# ServerTokens
# This directive configures what you return as the Server HTTP response
# Header. The default is 'Full' which sends information about the OS-Type
# and compiled in modules.
# Set to one of:  Full | OS | Minor | Minimal | Major | Prod
# where Full conveys the most information, and Prod the least.
ServerTokens OS

# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used.  If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
ServerRoot /var/www

# Mutex: Allows you to set the mutex mechanism and mutex file directory
# for individual mutexes, or change the global defaults
# Uncomment and change the directory if mutexes are file-based and the default
# mutex file directory is not on a local disk or is not appropriate for some
# other reason.
# Mutex default:/run/apache2

# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.
Listen 80

There’s a bunch more referred to in the number.conf relating to ssl that I havent included here, as well as some other ones but they’re all available here if needed.


I updated the server’s version of containerd & docker, the nginx-proxy-manager container and I also had a nice conversation with @discobot about capybaras - and now it works! I’m not sure which one was related to fixing the problem.

Anyway, what’s posted above here is a working config for a kirby alpine server behind an nginx proxy.

Hi! To find out what I can do, say @discobot display help.
