image not getting show on UI

[rg2609]

I am using the djangocms for the 1st and I am trying to add an image on the cms page, but it's not showing it's giving a 404 error.
Steps performed:

• pip3 installed djangocms-picture>=2.3,<2.5
• In INSTALLED_APPS added 'djangocms_picture'
• also sets following variables:

MEDIA_URL = "/media/"
MEDIA_ROOT = '/home/media'

CMS_MEDIA_ROOT = MEDIA_ROOT
CMS_MEDIA_URL = MEDIA_URL

Files get uploaded for the plugins and respected folders too got created but on the CMS UI, it's showing a 404 error. am I missing something or whats steps need to perform more to show an image on the CMS UI.
