How to avoid "No connection to TeamViewer server" dialog.

Hi,

I have various unnatended PCs that show information, these computers works without internet connection too, but when no internet access, appears the message "No connection to TeamViewer server" and interrupts the function of the screen. When the internet access returns, this message no apears, logically, but now I can´t check the checkbox "No show this dialog again", how I can disable this message? I not find this option in the configuration of Teamviewer.

Thanks

Best Regars
