VPN can't work on slimjet only

[swanpaul]

i have latest 35.0.1.0 x64 portable version of slimjet and i have try a new VPN service, free, Psiphon -- https://psiphon.ca/
but when i connect to this VPN and check my IP, it's always my real IP, but only with slimjet!
if i check my IP with brave, IE, firefox, chrome everyone has an IP that matches the VPN. only slimjet is not connected to VPN IP
why? and how to solve this issue?

I don't want to assume that you verified your VPN settings, then restarted your system and opened Slimjet up again and verified the issue continues?

yes, of course. problem persist

what i don't understand is why all my browsers are connected in VPN but only slimjet cannot ...

and you can try yourself, this psiphon VPN it's free and not required installation (only make your folder into \AppData\Roaming path), simply run it and check your IP
download from here https://psiphon.ca/psiphon3.exe

ok guys, solved!

from setting - proxy
if you set to use direct connection, it will show real ip
if you set to use system proxy, it will show psiphon ip
