Server stuck at loading terrain whenever trying to load into server

[HiyaHi]

I had this small server that i reserved for me and my friends to play vanilla survival. When i opened the server and activated it, i joined it. First time worked perfectly fine. But now, whenever i try to join it again, it gets stuck in the Loading Terrain, even while its activated.

Do you know if you are able to send the server logs. The logs can help to see what might be wrong with the server. Start the server, try to join it, and if it doesn't work, then check the server logs. Here is a tutorial on how to access logs if you don't know how. Then go to https://pastebin.com/, paste it there and send the link.
