Thanks for the response! I actually do have static addresses assigned, with Google's Public DNS server of 8.8.8.8 set for DNS. If the ISY continues to try to resolve the hosts, are successes listed in the regular log? Based on my logs above, there was an almost 2 hour period where it wasn't retrying or failing, yet it still showed as Offline in the ISY Portal, so I'd like to try to see what address it did ultimately resolve to if it wasn't the correct one.

My ISY is currently working fine, but I wanted to provide a bit more information and a suggestion to Michel, I've recently experienced a few brief power outages, and I've noticed once power is restored, the Portal isn't connecting for me, although the ISY is up and reachable on the local network. A reboot does resolve the problem though, This thread helped me figure out the problem, Thanks guys! From the logs it looks like its probably the DNS issue mentioned earlier in the thread. I think perhaps, in my particular case, it could be because the ISY boots up faster than my router, hence when it attempts to resolve these addresses it fails because it can't reach the Internet yet. The logs seem to indicate it retries a few times but then stops after a period (approx 1:45). Do you think it would be possible to add a periodic retry every 5 or 15 minutes after the initial cycle fails? This might ensure any other network gear has had ample time to boot up and allow traffic to pass again, and could prevent us from having to manually reboot the device when a new DNS query attempt could be made automatically. It might help enhance the recovery and I would think could be fairly easy to implement. Even adding a manual "retry DNS query" option in the Admin Console would help too. Although its quick, a full reboot is not ideal if there are less intrusive ways the problem could be resolved.
