Not able to connect VPN with SNX

Guys, good morning!
I am newcomer to the group.
I have a difficulty at the moment and would like to know if could get help here.
I need to establish a VPN to work from home.
Step by step,
first I install the necessary libraries ok, with the command:
- sudo apt-get install libgtk2.0-0:i386 libx11-6:i386 libpam0g:i386 libstdc++6:i386 libstdc++5:i386 libnss3-tools
Ok with the certificates' import:
- keytool -importcert -noprompt -keystore /local-path/vpn_cert.p12 -alias acus_v1 -file acus_v1.der
- keytool -importcert -noprompt -keystore /local-path/vpn_cert.p12 -alias raiz_v3 -file raiz_v3.der
Then I download SNX:
- wget /remote-path/CSHELL/snx_install.sh --no-check-certificate
And make it executable:
- chmod +x snx_install.sh
Hence I get the msg "Installation successfull" when I install with:
- sudo ./snx_install.sh
And when I try to establish the connection, with the command:
- sudo snx -s remote-site -c /local-path/vpn_cert.p12
I inform the password of the certificate and receive:
- SNX: Connection aborted.
or
- SNX: Authentication failed.
The password is correct, because I am using the same certificate file to log in via windows.
(a shame to have to use my girl's windows note to establish the VPN at work ...)
Thank you in advance!
