When trying to allocate a floating IP in openstack (on Ubuntu 18.04.1), I'm getting this error. "Danger: There was an error submitting the form. Please try again"
In /var/log/apache2/horizon_error.log, I can see the following message. 2019-01-30 15:57:55.500972 Timeout when reading response headers from daemon process 'horizon': /opt/stack/horizon/openstack_dashboard/wsgi.py
It seems to be the same issue as in the question below.
Workaround seems to be to add WSGIApplicationGroup %{GLOBAL} which I have already in /etc/apache2/sites-available/horizon.conf
I don't know what else shoudl I modify.
WSGIScriptAlias /dashboard /opt/stack/horizon/openstack_dashboard/wsgi.py WSGIDaemonProcess horizon user=stack group=stack processes=3 threads=10 home=/opt/stack/horizon display-name=%{GROUP} WSGIApplicationGroup %{GLOBAL}
SetEnv APACHE_RUN_USER stack SetEnv APACHE_RUN_GROUP stack WSGIProcessGroup horizon
