Automatic SSL VPN Tunnel does not work anymore (certificate ignore parameters)

FAQ followed and it has worked like this for years:

I use this for the automatic VPN tunnel setup for the backup clients outside at home.

For 2 months now, the parameter -i -m -q has no longer worked, which says "do not display a certificate message", i.e. the message always appears and no tunnel is automatically set up, i have v7.23.

Tried:

Then I downloaded the latest version 7.42 Fortitools and adjusted the command and then the parameter -u "enter user data according to text file" doesn't work anymore and no tunnel connects, but when i type in the credentials manually it works and no certificate warning comes - but automatically is needed.

It almost seems as if Fortinet has tightened security here "no stored access accepted" and in the old version "certificate must not be ignored" disabled?

I need an automatic VPN tunnel setup because of the weekly backup from the target client. What is your solution?
