I had the same problem for about a week, then I did this which solved my problem
I changed the server To France. not sure if this did anything but did it anyway.
Also renamed the Servers to something different from what I had already named it
Also, Clean Save Folder ticked to clean servers.
PLEASE NOTE: This will remove all of your save data (buildings, characters, items,).
Saved & reloaded the Server then All worked as intended
