Server unable to connect, and many issues with starting, restarting server

Recently, I've been facing alot of issues with the server. But mainly being the server unable for me and my friends to connect to. Yes I've double checked the IP, yes I've tried dyn IP, yes I've tried DNS, but non of it works for me (and all of my friends). It often takes 1 to 5 restarts to make the server work again. Many of the times I start up my server, it just stuck in the "starting" state, or in "restarting" state if I'm restarting.

Server: crinccc.aternos.me

I tried everything there. Literally said it in my post

Yes, I said I tried everything in https://support.aternos.org/hc…nable-to-connect-to-world

Yes, I kept it the same pretty much from the beginning of my server. Problem is that not only I am not able to connect, but all of my friends too. Also another problem that appears few days ago is that sometimes people just get randomly disconnected from the server, 1 time the server even shut down (shown offline in minecraft)
