ᐅ Issue with IKEA siphon – please take a look

Hello,

I’m having major issues with installing the siphon. Can someone tell me if I have connected everything correctly?
It leaks where the siphon meets the straight pipe under the sink; I hope you understand what I mean...

I don't understand where the leak is.
With the Atlantis siphon, the hose must connect directly to the drain and must not sag.
