what to do about chunks not loading? [duplicate]

Sometimes not loaded chunks create holes in the world. Why is it that some chunks don't load while everything around them gets loaded? Yesterday i traversed such a hole flying, it still didn't load. Is there anything that can be done to avoid such things? It destroys immersion, apart from that chunk being unusable while not loaded.

There are three ways to fix a chunk error:

1. Log off and log on again
2. Press F3 + A
3. Reset your Render distance in display options

Sources are here and here

Edit: As additional information, option 2 and 3 forcibly reload all chunks.

Three ways to help chunks to load

1. Try resetting your world. The chunks may not cooperate with how fast/slow your world is loading.
2. Check your render distance. Make sure your world is not too many/less chunks.
3. Check your WiFi. Another reason your world may not be loading fully is because of WiFi. If you have 2 or less bars, (or none) your world will not load. Try resetting your WiFi if it is running slow.
