Why does it never rain on my Minecraft server?

The gamerule doWeatherTick is true.

People sleep every night. Is this preventing rain?

Yes.

According to the Official Minecraft Wiki:

Sleeping changes the time of day to sunrise and resets the weather to clear weather.

If an administrator previously used /weather clear 99999 it's possible that the timer is still going. You could reset it by setting the weather to rain for a few seconds and it should go back to normal.

There are also some biomes where it doesn't rain - all the dry biomes, even in vanilla minecraft.

I always forget Savanna counts as dry when it has grass and trees everywhere, if your base is in such a place you'd never know when it was raining elsewhere.
