Hi there,
I managed to access my NAS and its various services form the WAN with a valid LE certificate. However, this certificate causes problems when my devices are within the same LAN as the NAS. E.g. on a windows machine, I get warnings and alarms from my malware protection solution, or from the browser itself. Even more problematic: Synology's DS Note app (and others? Not sure) is unable to connect to the server and sync. However, deactivating the Wi-Fi and using my 4G data plan is OK. That's not convenient at all.
Some web sites suggest this is due to a DNS loopback issue. I could find some tutorials explaining how to set up a DNS server on the NAS itself, but the given examples are never based on the same problem I have and I didn't managed to have this work.
So my two questions are:

So my two questions are:
- Is the DNS loopback diagnostic right, or am I on the wrong way?
- Do you know any (beginner friendly) resource that could help me with this issue?
