Bloom Web App : SecurityError

Hi everyone !

I currently try to set up the Bloom Web App locally (following this documentation : Installation - Neo4j Bloom), but I got this message when I launch the "index.html" file and try to connect to my Neo4j Database instance :

Does anyone know how to fix this problem ?
I've searched on this forum and even on Google but I couldn't find anyone who got the same issue. :frowning:

Thanks a lot by advance !

Best regards,

The web server conf doesn't match your server hostname or where you put the files to server up?
Post your conf file maybe?
