FortiClient won't connect

[doug_dockter]

I have a user at another location who has been able to establish an IPsec VPN connection to our Windstream cloud firewall previously.  She is currently not able to connect.  I've attached the log file. I've verified that I can establish a connection at another workstation with her credentials.  Any help would be appreciated.

I'm not too familiar with IPSec vpn debugging with FortiClient since we use FC only for SSL VPN. But first you need to set the log level to "Debug" to see more detail. Based on what it shows now it seems to be able to get the initial response from the server side successfully but not beyond that point, and repeat the attempt three more times and drops. You likely need to sniff or debug IPSec on the server side if you have access to the server end. If not, you need to ask Windstream.

Under the forti-client file it says a network error prevented updates from being downloaded. We have connected nightly for three years from here same isp. Version 5.4.0.0780 and one is 5.4.3.0870
