Table C.1. Common problems in Red Hat Update Infrastructure
| Category | Issue | Solution |
|---|---|---|
| ISO Download/Red Hat Update Infrastructure Certificate | You cannot download the Red Hat Update Infrastructure ISO from the Customer Portal with the RHUI Certificate. | Verify that RHUI entitlements are in place and enabled in your Red Hat Network account. Verify the credibility of the certificate being used to download the ISO. Make sure the certificate is a RHUI consumer certificate; follow the instructions in the Installation Guide for creating the appropriate RHUI consumer content certificate. |
| Red Hat Update Infrastructure Certificate | You see an error message while uploading Entitlement certificate using rhui-manager. | See While uploading entitlement certificate on RHUA using "rhui-manager," it fails with "IndexError: list index out of range" for more details. |
| Installation/Configuration | You experience communication issues between the Red Hat Upate Appliance and the CDSs. | Verify the fully qualified domain name (FQDN) is set for the RHUA and CDS and is resolvable. Configure the HTTP proxy properly as described in Bug 726420 – Quick note on proxy URL |
| Synchronization | You cannot synchronize repositories with Red Hat. | Verify the RHUI SKUs are in your account. Verify the proper content certificates are loaded to the RHUA. Look for temporary CDN issues. Look for any HTTP proxy in your environment and make sure you are not hitting an While syncing repositories to RHUA, it fails with "RepoError: Cannot retrieve repository metadata (repomd.xml) for repository. Please verify its path and try again" when proxy used error. The RHUA cannot synchronize to CDSs, typically due to expired qpid certificates: See CDS sync fails with error "sslv3 alert certificate expired" due to expired qpid CA certificates on RHUI for more information. |
| Red Hat Update Appliance/Content Delivery Network Communication | The Red Hat Update Appliance is not communicating with the Content Delivery Network. |

Note from the curl (1) man page: If the NSS PEM PKCS#11 module (lib-nsspem.so) is available, then PEM files may be loaded. If you want to use a file from the current directory, precede it with

| Client/Content Delivery Server Communication |

|
| Content Delivery Server Synchronization | The CDS synchronization fails with SSL errors because of expired Qpid certificates |
CDS sync fails with error |
| Client/HAProxy communication | All HAProxy nodes are down. Clients have lost access to RHUI repositories. | Add and configure at least one new HAProxy node. If you cannot do so for whatever reason, temporarily change the DNS configuration so that the main load balancer host name (cds.example.com in this guide) resolves to the IP address of one of your CDS nodes. This will allow the clients to avoid the unavailable HAProxy nodes and communicate with the CDS directly. |
