My server restarts alone, what can I do?

Same With Mine Everytime I get on the server shuts down and then i have to force stop mine and re-resart it again

is it an atlas server if it is you might not have any expansions linked and or mods might be missing or corrupt

Hello

If it's not what LadyGator suggested and its a regular public server the best action would to submit a support ticket as we do not have access to servers or account on the forums.
