Did you know that the VMware Learning Zone offers 600 technical videos, 55 short self-paced courses, and VMware Certified Associate (VCA) training all for free?  One of the best free resources available on the VMLZ are the 5-Minute Fix videos.  These are really short (like 5 minutes or less) videos by expert VMware employees that show you how to fix an issue you may having with a VMware product. These videos cover the top KB articles across all VMware solutions.  And best of all, yours truly, Team Kandy, contributed to some of the videos for vRealize Automation.  You’ll need to sign up for the Basic subscription (which is free) but even as a guest, you have access to some of the videos.

Mandy produced a series on disabling TLS 1.0 in vRealize Automation components, which are based on two KB articles: https://kb.vmware.com/s/article/2145796 and https://kb.vmware.com/s/article/2146570. You should note that there is not yet a video to show you how to do the RabbitMQ fix but I suspect after watching the others, you will be able to work it out.
