Hi all,

When attempting to access my mesh network using DDNS, example - "xxxxxx.tplinkdns.com", I receive the following error - "Rejected request from RFC1918 IP to public server address."

By extension, I have a Synology DS220+ that I can not access by DDNS either, it results in an identical error to what is above, leading me to believe that the issue may well be linked. (I apologise if it is the case this is a seperate issue, the mesh network is my primary focus with this post.)

I have wiped/reset both the mesh network (comprised of S4s and E4R units) and the network settings on my NAS to no avail.

In terms of how I have the DDNS setup, I use the Deco app.

Seetings -> Advanced -> DDNS - DDNS option is set to True, and I have my domain name set in the format "xxxxxx.tplinkdns.com".

This all used to work flawlessly, so I am a bit puzzled!

Any help would be great,

Thanks in advance,

PJ
