please, please, please DONT use SSLv3. it has been unsafe for a long time, it should NOT be used.
 
if you follow any SSL/TLS related news you see that browsers are stopping support for TLS 1.0 and TLS 1.1. that is for a reason and SSLv3 has seen that happen years ago.

Same issue with my connection. TLS 1.1, 1.2 and 1.3 were checked since FortiClient installation. I was connecting to my office during weeks without any error. And then VPN connection fails without doing any changes in my configuration. After different attempts with other solutions without success, I've unchecked all these options (TLS...) and try connecting with, obviously, no success. Then I've checked them again and vpn connection is now OK. Strange things...

That looks like you do not have split tunneling on your vpn plus some means of auto detection on your network interface. This causes you defalut route to be rewritten and then the auto detection gets this an disables or disconnect s your wifi. Some Laptops do this. I once ran into something similar on my laptop when it kept disabling my wifi when ethernet was connected. This can be a bios option and also some manufacturers install some windows service for it.
In my case only disabling that service in windows 10 finally prevented my wifi from being disabled.

Greetings,
I too was getting this error.   For me it was the password length.  The original passwords were 16 characters, after dropping the first four (12 character length), the VPN was able to connect.
Seems silly that an industry leading security appliance throws an ambiguous error due to password length.
Tested, confirmed and verified on five different accounts in the same VPN GROUP...
 
Your mileage may very, but thought I'd share...
Jim

thank for sharing Jim.
 
i dont fully agree with the comment of providing limited information to the client, as this can be used to launch an attack.
 
still the message could be more general, failed, contact your administrator, now it points to something which it often is
