ntopng | unable to export configuration | error: couldn't download network issue

[z0rk]

I am attempting to export my ntopng configuration settings.

Web Gui
Settings > Configurations > Manage Configurations > Configurations
> select: Entire ntopng configuration (includes users, preferences, and all configurations below)
> select 'Export'

Browser download manager error (independent of browser type/version):
couldn't download - network issue

I've also noticed that no backups of configuration settings are being generated under
Settings > Configurations > Manage Configurations > Nightly Backups

Thank you
