WAN Down but logs show DDNS updated and DNS lookups successful

Hello Brian1941 ,

Thank you for reaching out to the community, have you created an static DNS host entry ?

Vivek Jagad I have static DNS entries, what does that do to this issue?

Hey Brian1941 ,

Can you share the screenshot of the DDNS configured ?
Can you also share the ddc.log and dgd.log during the same time when WAN was down but DDNS got updated.
To check the log file use the doc for the reference.

Vivek Jagad Please see private message, thanks.

Hey Brian1941 It might have been a DNS cache resolver that made it work, thus concluding this thread
