Cannot climb the Volcano

Good Day. I have a Saris Fluid2 with a Saris speed sensor and an old bike. I like to ride for fun on flat route (no race) at a leisure pace. I just tried the Volcano Climb and my bike is barely climbing up and keep it at 2-5kpm even if I pedal hard/non-stop. What can I do to fix that? Thank you for your help!

You need to increase your watts.
