While building a new freeipa server in AWS I got this error:
2018-03-01T18:15:49Z DEBUG The ipa-server-install command failed, exception: RuntimeError: Certificate issuance failed (CA_UNREACHABLE)
2018-03-01T18:15:49Z ERROR Certificate issuance failed (CA_UNREACHABLE)
2018-03-01T18:15:49Z ERROR The ipa-server-install command failed. See /var/log/ipaserver-install.log for more information

I did some research and found this is possibly related to version 4.5.0?  

I have a host entry in /etc/hosts but that didn't seem to fix the problem.  Is there something else I'm missing?

Do you know when 4.6.x will be released to epel/amazon?

Thank you,
Andrew
