EAS Console not available

Hello,
It happened one time that the EAS Console was not available and the OHS log files showed errors like :

[2013-06-14T10:29:58.5059+02:00] [OHS] [ERROR:32] [] [mod_weblogic.c] [host_id: xxxx] [host_addr: xxx] [tid: xxxx] [user: xx] [ecid: xxxxxxxxxxxxxxxxx] [rid: 0] [VirtualHost: <hostname>:xxx]  ap_proxy: trying GET /easconsole/easconsole.jnlp at backend host 'xxxxx/; got exception 'CONNECTION_REFUSED [os error=115, line 1582 of ../common/URL.cpp]: apr_socket_connect call failed with error=111, host=xxx, port=xxx '

We verified the logs as it seems that need to check if all apps are up etc. There is nothing in the logs corresponding to this time
