1.16.3 cant connect to my own realm

I'm currently having and issue where I cant join my realm server, I can join friends servers but not my own. It leaves me an error saying "io.netty.channel.AbstractChannel$AnnotatedConnectException: Connect timed out: no further information"

I logged into the server the previous day but cant no more, neither on main account and secondary account, and I can join any other realm. Just not my realm is working.
