Hi, I just migrated my Jira instance from Azure VM to Amazon EC2 instance, I followed this link and I migrated my Jira instance successfully then I've installed PostgreSQL to my Ubuntu machine after that I've chosen " I'll set it up myself. " then on database connection step I've chosen "My Own Database (recommended for production environments)" after that I filled from with my database credentials then Jira stuck there. Even worse I'm not able to connect my EC2 instance with putty nor WinSCP. to connect my server again I have to reboot it. After the reboot, I'm starting Jira and the database Jira stuck "Atlassian JIRA is now ready." after that Server is going down. Does anybody know what is wrong with that?
