Issue
- While trying to enable remote staging by using two separate Liferay instances and everything is configured, we receive the following error in the console logs:
DEBUG [https-jsse-nio-443-exec-3][StagingConfigurationPortlet:183] com.liferay.exportimport.kernel.exception.RemoteExportException: java.net.SocketException: Unexpected end of file from server
com.liferay.exportimport.kernel.exception.RemoteExportException: java.net.SocketException: Unexpected end of file from server
Resolution
- Based on the information here, "Unexpected end of file" implies that the remote server accepted and closed the connection without sending a response. It is possible that the remote system is too busy to handle the request, or that there is a network bug that randomly drops connections.
- Please try to check your connection - e.g. if you have a firewall, try disabling it temporarily and try the configuration again.
