@lickdragon - the Let's Encrypt CA doesn't distribute a CRL (there's literally not one listed in the CA's certificate), meaning there's nothing for Xrootd to retrieve. @gganis - in this case, can we have CRL mode "3" simply ignore the lack of a CRL? -- You are receiving this because you are subscribed to this thread.
