I did hit the following issue on one of my controllers:

In horizon.log:

[IP:39466] compressor.exceptions.OfflineGenerationError: You have offline compression enabled but key "dad03ce06cb01a989fde7e905c986a37847a72819bd3221fbb378833292ab128" is missing from offline manifest. You may need to run "python manage.py compress". Here is the original content:

My workaround was to run that command inside the docker container:

(horizon)[root@controller /]# /var/lib/kolla/venv/bin/manage.py compress
/var/lib/kolla/venv/lib64/python3.6/site-packages/scss/namespace.py:172: DeprecationWarning: inspect.getargspec() is deprecated since Python 3.0, use inspect.signature() or inspect.getfullargspec()
  argspec = inspect.getargspec(function)
Compressing... done
Compressed 7 block(s) from 12 template(s) for 0 context(s).

and then restart it:

[root@controller horizon]# sudo docker restart horizon
horizon

I did a service deploy and not an upgrade or reconfigure; could that explain it?
