I'm thwarted from installing OCP 4.2 on OSP 13 due to lack of support for a typical enterprise TLS config . It is preventing the bootstrap node from reaching Swift due to "self-signed" cert. I see that may be mostly fixed upstream  now.
If this fix is in a nightly build  of OCP 4.3, how do I, as a customer obtain access for testing? Following the link in the blog post to try.openshift.com
does not seem to offer an answer. RH tech support does not seem to realize it's a thing or I'm bad at asking questions. Nightlies of OCP is a thing, right? :)
