AutoSSL HELP MASTER DCV: A rate limit prevents DCV

We have seen a couple reports of this in recent weeks. The Pending Authorizations points to a problem in AutoSSL or its configuration. See this thread for comments from staff. Probably not the same cause but maybe gives ideas

This was another report but not much to help you (just reference). I don't remember seeing any of these and now several in the past weeks. Hmmm.
