After kill one node of a cluster which consist of three nodes, I found that Horizon based on keystone with provider set to fernet respondes very slowly. Admin login will cost at least 20 senconds. And cli verbose command return show making authentication is stuck about 5 senconds. Any help will be appreciated. -------------- next part -------------- An HTML attachment was scrubbed...
