Hi all,

i'm having same the issue reported in BUG  OP-15480 
I've tryied all solutions proposed in bug answer, but none of them solved: i still get the error message "Invalid host_name configuration"
My operproject is 14.6.1 on Rocky Linux 8, and use RPM package version. Proxy is done with Apache.

I've also tryed to add a "ServerAlias" clause in Virtualhost config section, but no change.

Follow my config: i hope someone can help me to understand where i'm wrong:

1. The contents of /etc/openproject/installer.dat

2. The contents of /etc/httpd/conf.d/openproject.conf

3. The value of openproject config:get SERVER_HOSTNAME and openproject config:get OPENPROJECT_HOST__NAME

4. The contents of /etc/openproject/addons/apache2/includes/vhost/ssl.conf

1. /etc/openproject/installer.dat
