Is there a method to change a chosen option to use a single FQDN to instead avail the Internal FQDN/IP and External FQDN instead without backup/reinstall? I apparently derped on this last install.. assumed there was some local/internal DNS host available.. there isn't. Can I adjust custom params for this? If so.. let's assume I'm happy with the external FQDN (I am..) and need a local IP (since again I don't have local DNS..). I ask because it ties into the next possible question about re-using one of those issued Let's Encrypt certificates.. I'm afraid I won't be able to use the same host name if I retried the install without calling support.. and unsure even if then. On this bit.. I'll be pursuing the CSR/PFX option.. but also have a question out about replace/renew on those (three years can go by fast..). Else.. I'd just have backed up and done over with changing that DNS question accordingly..
