FVS318N - Clock skew detected
Model: FVS318N Firmware: 4.3.3-6 Problem: IPSec tunnel to PFSense router constantly fails and drops internet. Requires hard-reboot for it to come back up. This is a 4+ times a day thing. This ...
Hello morris_aiu,
Welcome to the community!
I have seen this error before, it appears that this is caused by the Time Zone not matching thier locations. If you have a box-to-box VPN configured, check each end and make sure that they are on the correct time zone. For FVS318N go to Administration>Time Zone.
Let me know if this helps.
Thanks,
JohnRo,
I've checked all of 6 of our FVS318N's that are having this problem.
They were all showing the correct time, and correct time zone.
Also noticed on a reboot all logs start off in December, until it syncs with NTP servers.
I appreciate the reply!
Hello morris_aiu,
Please try the steps below and see if they will make any changes:
1. Boot the router and disconnect all established tunnels
2. Properly sync the time either using NTP servers or manually(using Authoritative Mode). - If the settings are already correct, just click on "Apply"
3. Soft Reboot the Device using option "Reboot the Router" in "Monitoring -> Diagnostics"
4. After device got booted up, Connect the Tunnels.
5. Then test the issue.If this will not solve the issue, you may have to open a ticket with our support team.
Thanks,

Hello completed steps 1 through 5 to no avail sadly. Still getting the errors, and IPSec tunnels dropping left and right. After reboot and checking the logs, nothing but the 'Clock Skew Detected' error.
This has now started affecting a few more locations as well.
Any other ideas?
