@mfuglem, if your environment is having issues updating external content sites to the latest versions, you can leverage the Airgap utility to resolve. For example, if you were to see “failed to pass sha1 hash value checks” errors in your BESRelay.log it indicates that something between your root server and the BigFix sync servers has in someway modified the site download. This could be content filtering and or proxy config in your environment. Running the Airgap process will allow you to mitigate these issues. Utilization of the Airgap utility does not mandate the BES environment not be connected to the Internet.
Have you checked the BESRelay.log and GatherDB.log on your root BES server to see if you’re getting errors when trying to import version 1234 of the “BES Support” external site?
