Server Glitching in weird ways

[Tromon]

I have a problem with my server

When I get on my server everything is frozen (Mobs, Redstone etc) I cant interact with things (chest, Beds, etc) and only some chunks are loaded in. When this is happening I can move around normally. After this happens it kicks me from the server and says "Couldn't connect to a default or fallback server, please try again later:  io.netty.channel.AbstractChannel$AnnotatedConnectException". After a few minutes the server goes into a offline state. This started when I set the random tick speed to 99999999 (I have treid changing it but it wont work)

Please help I am very confused

You can fix this by going to your Dashboard, and under Send console command (Appearance tab) paste the command gamerule randomTickSpeed 3 after starting <-> Before joining the server
