Did you copy over the include/ost-config.php file to the same location in the new directory? Did you ensure all files and folder have the appropriate permissions/ownership? Did you copy over any and all plugins from the old location to the new one?
If all that checks out check all possible logs for any related errors (general server logs, webserver error logs, PHP error logs, MySQL/MariaDB error logs, osTicket System Logs, Browser Console logs, etc.).
Cheers.
