VPN SSL Stuck at 48% error -455

Hello,

 

I encounter a problem on one on my VPN SSL connection. 

I've a "permission denied" error message, stuck at 48% error -455.    I try on another computer, with the same account, it's functionnal. I try on 6.0.9 and 6.4.1 versions and it's functional.   I get some logs :
