Cubecraft servers are still on 1.9, so shields don't prevent knockback and only reduce the damage. If you get hit with an axe while blocking, your shield gets disabled for a short time, you can see the cooldown on the shield icon in yout offhand.
Also when you get hit while blocking you have a chance of the shield glitching, causing you to keep blocking forever from other player's prespective and being unable to hit.
