Not sure if an old bug has regressed back,
I have been having fun sorting out SOGo for Exchange Sync and noticed the:
/etc/apache2/conf.d/SOGo.conf
<Proxy http://127.0.0.1:20000/SOGo>
## adjust the following to your configuration
RequestHeader set "x-webobjects-server-port" "443"
RequestHeader set "x-webobjects-server-name" "yourhostname"
RequestHeader set "x-webobjects-server-url" "https://yourhostname"
These need to be manualy set after instalation (not mentioned in the main install guide)
or the hostname replaced during the install script as per post.
