Greetings,

we have some certs expired on Dec 27, ipaCert among them, IPA (VERSION: 4.4.0, API_VERSION: 2.213) stopped working.

I have spent many hours to renew the certs to no avail.

I have followed a collection of tips on this list:
 rolled back the clock to before the expiry (Dec 23), 
 enabled debug logs for certmonger renewal log (getcert modify-ca -c dogtag-ipa-ca-renew-agent -e '/usr/libexec/certmonger/dogtag-ipa-ca-renew-agent-submit -vv')
 added debug=true to /etc/ipa/default.conf
 
 ipactl start starts everything successfully
 systemctl start pki-tomcatd@pki-tomcat
 systemctl restart certmonger

Before resubmit, "getcert list" has this, note ca-error: Invalid cookie: '':
