Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

setting a default value to [5] resolves the issue.

this seems like a regression in #27160.

Comment 7 Bryan Kearney 2020-01-12 13:01:08 UTC 
Moving this bug to POST for triage into Satellite 6 since the upstream issue https://projects.theforeman.org/issues/27585 has been resolved.
Comment 8 Tomer Brisker 2020-01-12 13:36:20 UTC 
This is caused by an upgrade of a system that has the `dns_conflict_timeout` set to the default value. in some cases, it can cause the upgraded system to have the setting `dns_timeout` set to `nil` or `[nil]`, which causes any dns lookups to fail.

To verify:
1. On Sat 6.6, Make sure `dns_conflict_timeout` is set to the default value (`Setting.find_by_name('dns_conflict_timeout')[:value] == nil`)
2. Upgrade to 6.7 
3. Make sure `dns_timeout` setting is set to the default value (`Setting.find_by_name('dns_timeout')[:value] == nil && Setting[:dns_timeout] == [5, 10, 15, 20]`

Make sure to run 

Rails.cache.delete(Setting.cache_key("dns_timeout"))
Rails.cache.delete(Setting.cache_key("dns__conflict_timeout"))

between steps to ensure the cache is cleaned.
