Hello,

trying to update to the latest AIRAC cycle but the FMS Data Manager (v1.8.14.0130) always says “no internet connection” although the connection is working (otherwise I could not write this post). Please find screenshot and logfile attached.

Please try:

Restart the machine.

Disable any Antivirus and firewall.

If still no joy, try connecting to the internet via a mobile hotspot.

Cheers

Ian

HI Ian

thanks for your reply. I did all of your suggestions but to no avail. Neither with AV switched off nor with an explicit exclusion to the FMS Data Manager.exe it works.

FMS Data Manager worked for years on this computer without any hick-ups. Now - out of the blue - it can no longer find the obviously working internet connection while all other programs are running properly and connect with the internet.

From a technical standpoint, what makes this program different from all the others, given that it doesn’t have Internet access?

Any idea on how to get the latest navdata?

Cheers  
Urs

As a workaround please use [ManualDownloads](https://navigraph.com/downloads)

Thanks Ian. Sorry for the dumb question … I should have scrolled down a little further.

Cheers
