This can mean there is a communication problem between workspace and obiee, have you validated the servers can communicate e.g. ports, firewall, server
Is the configuration correct in epm.conf for 18.104.22.168 or httpd.conf for prior versions.
I have installed both OBIEE and EPM on the same server
i have updated Proxy information in httpd.conf.
I am using Hyperion 22.214.171.124 version, So now opened the epm.conf file. I have proxy information in the epm.conf(I think its automatically updated may be)
