Re: Unable to establish the vpn connection. the vpn server may be unreachable. (-8)
Just wanted to add,
had the same issue with some users yesterday,
reset the password and was ok again. (might be the issue of the password never expires option)
Today working from home, same issue, didn't change my password, I just pinged the VPN server, after that I could connect again with Forticlient. (might be the resolving of the FQDN)
- reset password
- ping the vpn server
I'm no expert, just wanted to add the stuff that worked for me.
