Lab: H2.CL request smuggling not solved

Hi I'm having trouble getting the mentioned lab to be marked as solved. This is my request: https://snipboard.io/c4Ms86.jpg I've also disabled all plugins and tried it with and without the integrated browser. I've also tied it without the newline at the end of the request.

Thanks for your message. We've just tested the lab and were able to solve it using the instructions given in the solution. You might find you need to send the request a few times before the lab is solved, try leaving a gap of around 10 seconds between each request you send. Good luck!

I was able so solve it eventually after sending the request for like 15min.
