My Rippled Server (AWS EC2 m5.large) stoped working

After creating an image of my Rippled server I migrated it to another region and started the server. At the beginning it was working fine but suddenly it stoped working. Don’t know really why. I tried to create new directories to sync the blockchain again but it is not working, the main process is childs one after another and not really doing much. I don’t think the resources available to this EC2 server are insufficient since the XRP Ledger webpage recommends a less capable machine to work with. Every time I try the command “rippled ledger_current” the response is always “Not synced to Ripple network”.
How can I proceed? What can I try next?

Thanks in advance
