FortiClient VPN issue

Hi all,

I am using FortiClient VPN to connect to Company network.

Last week we changed our internet provider and with this we changed our IP address.

In configuration of FortiClient VPN we setup server value as https://subdomain.our.domain . We changed DNS settings for this value to new IP and if I ping subdomain.our.domain I am getting correct IP address.

But, my FortiClient is always trying to connect to old IP and I get error "The response from:
https://my_OLD_IP was invalid."

If I reinstall FortiClient VPN then he will delete everything and Client will start to connect to correct address and everything will work. So he will start to resolve correct IP address.

My question is: Is there some way to delete this value without reinstalling FortiClient?

Also, if someone have experience with iMac devices - Uninstalling client is not helping with this.

Hi @RenatoM,

Have you tried delete the configured tunnel and add a whole new connection?

Yes. This was first thing which I tried.

Dear RenatoM

May I know whether the issue is happening for a specific Forticlient version?
Could you please remove the complete Forticlient using this tool?

And then try using a different forticlient version, post that try adding old IP and add the new one and verify the behavior.
