It is not always due to unneceary plugins.Sometimes just minehut is just lagging out your server.I would suggest to see if there is a unupdated plugin because about a week ago my server was crashing due to an unupdated plugin.But what Elektrodes you probably have a about 50 plugins and 1 gb of ram which is causing your server to not have enough ram to contunie.
You can contact minehut support if there your sure its either of the problems i addressed.
Have a good day!
