I just wanted to create a post to update the solution from this post:
The above post states Zammad does not work in an LXC container. I have two separate installs in two separate LXC containers.
I was getting the same error (from this post) after installing a second Zammad in an LXC container using the script here:
I went into the LXC container…
cd /etc/nginx/sites-available
nano zammad.conf
Changed the container’s ip address:
server_name 192.168.100.106;
To my subdomain:
server_name support.domainname.com;
Saved and exited.
Then:
nginx -t
systemctl reload nginx
That’s it!
To be clear, at this point I already had the subdomain created at my domain’s host, with an A record pointing to my router, and then the router forwarding traffic to my proxy. The proxy was already set up and had SSL certificates installed.
