Hello I am running CentOS 7.9 FreeIPA 4.6.8 Installed with integrated DNS and CA A replica will be installed after the trust is established with the AD domain. When trying to create a trust with AD i get the following error message (it seems to be somewhat random but goes back and forth between these two) Fetching domains from trusted forest failed OR ipa: ERROR: cannot connect to 'https://<server>/ipa/session/json': Gateway Timeout I have done the following to troubleshoot: - disable Selinux, which makes no difference - check firewall ports. for your reference I have the following defined services: freeipa-ldap, freeiipa-ldaps, http, https, kerberos, ntp, dns, ssh ports: 749/tcp, 7389/tcp, 8005/tcp, 8009/tcp - check DNS, it all verifies properly according to 5.2.1.2 https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/... - enabled debugging per https://www.freeipa.org/page/Active_Directory_trust_setup#Establish_and_v... - disabled DNSSEC per https://access.redhat.com/solutions/2263991 I do see something of interest in the error_log but I am not sure if this is the problem. wsgi:error Timeout when reading response headers from daemon process 'ipa': /usr/share/ipa/wsgi.py ipa: ERROR: Failed to call com.redhat.idm.trust.fetch_domains helper. DBus exception is org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. ipa: ERROR: Helper fetch_domain was called for forest <forest_name_here>, return code is 2 Any assistance you can provide is appreciated!
