Gateway certificate has expired

[Virupaksha]

Hi Guys,

While accessing the remote VPN, getting gateway certificate expired alert.

Error:Connection Failed

"Gateway certificate has expired. Please check your's computer time and date settings"

I have checked the VPN expiry date but it is 14th may 2021.

Can you please help me on this.

Hi,

Have you checked times on your computer and your gateway/management? Are you using NTP ?

Did you check defaultCert certificate inside IPsec VPN tab of the affected gateway ?

What warning you are getting once you install policy on affected gateway ? Or, are you even able to install policy on affected gateway ?

Do you have valid license? did you use eval lic in the past which may expire ?
