Mosaic: No automatically login if in intranet-mode

[Zen]

Hi, i'm posting this due i've got some trouble with Mosaic today. 
I've done these things:
- configured Mosaic with my items/widgets
- connected LM to cloud
- created a new mail/password access
- created a new connection string
- pasted the connection string under LM-cloud field
- installed the Logicmachine app in the smartphone
- configured remote access
- finded and configured (with password) my local LM5 in the same network

Now, if i'm disconnected from the local network and navigate with 3g/4g or another wifi network, i can easily access my lm5-Mosaic easily and instantly.
If im connected to the intranet, in the same network of LM, i can't access the machine locally nor remote. I've tryed changing the redirect page to see if something changes but i've not solved anything.
Can you try to help me out?
Thanks
Have a great day
