Nope, no other DDNS clients. Just Amahi.We really did not need to see the network specifics, just know that you checked them.
Probably not a good idea to share your HDA IP Address with the world. I presume that is the IP address your clients reflect.
Are you using any other dynamic DNS clients like no-ip.org or similar? Mixing them with Amahi could cause the issue you experience.
I thought I edited out the important information, but did not think my internal client ip addresses should be hidden. Thanks.
