Thanks for the screenshot!
The Sol on the right side should get you on the other side of the gap. You just need to do it a little bit later. This section is meant to teach you to jump at the right moment and to give you an opportunity to try again if you fall. The next gaps will be much more merciless mwahahaha!
Let me know if you really can't achieve it. That is the kind of things I might readjust later.
