Hi,

We are suddenly getting a blank page when connecting remotely to our server. Website home page is accessible. When we are on a local network this problem does not exist.

This is what we tried so far:

Restart Server

Restart database

Restart Odoo instance

upgrade web_tour module

Upgrade mail modules

Regenerate Assets Bundles (this one actually makes thing worse, site doesn't load CSS. Requires website module upgrade to bring it back)

Here is an error  from a Chrome console

owl.js:2939 Owl is running in 'dev' mode.

This is not suitable for production use.

Unfortunately we are not developers so any help would be appreciated
