Firewall XG86 VPN Connection failed

Suddenly when I reviewed the Firewall configuration XG86, the VPN connection for all VPN users had failed !! , I did the following actions:-

1-I restored the old configuration but did not solve the problem,

2-I updated to the latest Firmware but did not solve the problem

3-I deleted the current Firewall VPN rules and re-setup them again but did not solve the problem.

Any support Please
