IPA wait_for_open_ports: localhost [8080, 8443] timeout 300


IPA wait_for_open_ports: localhost [8080, 8443] timeout 300

Today we were updating the server with yum update on our IPA server.

The yum update finished successfully, but the IPA was not starting after the upgrade. the ipactl restart was also throwing an error. The web interface came up after the server restart but it was throwing “unknown error” while trying to log in via the web interface.

Below is the error from /var/log/ipaupgrade.log

As recommended on the error log, we tried running ipa-server-upgrade command but it was throwing the same error as above.



  • We have verified that the telnet on localhost port 8080 and 8443 is working fine.
  • Tried disabling SELinux and firewalld and rebooted the server, The issue was not solved.


As we checked in detail, it turned out that the client had disabled IPv6 on the kernel as a part of PCI DSS Benchmarking. But the /etc/hosts entry for ipv6 localhost was still on the hosts file.

::1             localhost

the solution was to remove the above entry from /etc/hosts file and rerun the ipa-server-upgrade command.
