Stop constant rain on my server

When I logged in today into the server it started raining soon after and had been raining for hours, even till I logged off. In between I tried /weather clear command twice but it again starts raining after some minutes. I need the rain to stop for my bees to come out and so that my bee farm works. Also I don't like rain. Is there a way to turn off rain?

(I have tried /gamerule doWeatherCycle false but it does nothing. And yes I am the OP of my server)

Hmm I did try that some times but for some reason it didn't work. I'll still try it again today and update about it
