Debian - Device is offline at different subnet

Hi,

I'm using teamviewer-host_14.7.1965_armhf.deb installed on Debian.

I can connect to the remote controller easily when it is connected to 10.16.1.x. network.

When I connect the same device to 10.16.8.x network, I see the remote computer as offline always.

I have the same host with the same Linux and Teamviewer installed on different host that works fine with all networks , the only different is that the host that doesn't work, have "access point" and modem configured.

What can cause this problem?

Thank you very much.
