@alan6854321 , Yes. The "DDNS was updated" flag gets cleared when the connection goes down. When the update is triggered, the first update fails (probably due to timing), which triggers the watchdog retries. The pre-update checks determine that IP hasn't changed, and exits without setting the flag back to "updated", which causes the watchdog to keep retrying. That's at least the chain of event Asus could determine in their analysis of the issue, we'll know for sure once you test it with a fixed build.I wonder if the repeated DDNS restarts I'm seeing only happen if the WAN reconnects AND the IPaddress is unchanged?
