comment Oracle 12c Express Enterprise Manager on Centos 6.5 is not reachable
Does your server have multiple network adaptors? Check listener.log at the time you try to connect to the webpage. Does it contain a TNS-12518 error? Is the IP address mentioned in this error the same as the IP address your hostname maps to? Or is it the IP address of one of the other adaptors? Is the problem solved if you disable the other adaptors?

comment Oracle 12c Express Enterprise Manager webpage does not load
host_address returns an ipv6 address, the host returns the hostname in uppercase, without the domain attached. I've also ran an RDA report, and that showed "DNS Lookup - FAILED". Also, Cloud Control fails to install when using the hostname, but works when using the IP address. I'm now certain this is some kind of DNS issue, I'm just clueless on how to debug/analyse...

I'm running all tests on the db host. Pinging hostname and ipaddress, and tnsping to CDB and PDB's works fine. Nice catch about the refused connections! I've restarted the listener, and used the hostname-EM-URL: same problem "webpage not available", and lsnerctl shows no entry yet for XDB. When using the ip-EM-URL EM loads (slowly) and I get an XDB entry, but no refused connections. I have no idea what to make of this, but maybe it does to you?

comment Are all Oracle DB Control features available in Enterprise Manager Express or Cloud Control?
Great, then I know I don't need to bother trying to fix my broken EM Express... If you post your comment as an answer, I'll accept it...

Any idea on how to debug, track the exact cause?

The hosts file is empty. Not sure how exactly the hostname is managed, but the network uses an ActiveDirectory server where the server is registered with its hostname, and the DNS servers recognise it as such.

comment where is the oracle 12c logfile?
I think the question is useful in terms of "where is the log file". But the sub-question about the idle instance should just be removed from this question to improve the quality, no?
