Dynamic DNS not updating

My router (BT Smart Hub Type A - also known as HomeHub 6) includes a ddns client that was working, but now I just keep getting the very unhelpful error message in my router logs
Code:
pp1:DDNS ERROR!!client:1 DynDNS update server error. Retry in 30 min.
I was originally using my account password but I've swapped the password auth with the token auth, and there has been no change in behaviour.

On the zoneedit site, I can't seem to find any information at all about why the requests are getting 'update server error', the page at User > Security > Activity Logs is completely empty even though I am sure there should be some activity, is that a paid feature? The router does not tell me what the error is or show me the response body so how can I find out what's going wrong? When I log in to the zoneedit site I see that one of the two hosts it should be updating has been successfully updated, but the other has not. I can't find anywhere on the zoneedit site where I can verify when or how that was updated.

Why are the activity logs always empty and how can I find out what the error is?

hi there on the zoneedit page the security options. .. there is no Activity Logs option.. is that on your router?

what is the domain name of concern?

ahh yes sorry that one is preference enabled.. once enabled it will list logs selected in the Activity Notifications section but i do see that it does not seem to be operational presently I have opened a dev ticket on that... that said it would list DNS updates but would not specify if dynamic or not. on your current zone file can you please change the TTL on dynamic records to be no less then 10 minutes or 600 seconds... can you send in a screen grab of your router config for dyn updates.

regards.

Setting the TTL that high kind of goes against the point of using dynamic DNS, and doesn't sound like it would have anything to do with 'server error' when the router requests the update. I've done it anyway but it hasn't changed the behaviour.

I have the most recent logs available now:

it looks fine actually:

yes, but again there is nothing in that log entry about cloud.35uu.cf, only 35uu.cf, and my router logs has the same error again, and the ip for cloud. was not updated.

also your log doesn't seem to be correct - it says it made 3 new DYN records and had 0 errors, but I'm only trying to set 2 records and only one is succeeding, and my router reports 'server error'

first off .. activity logs now works :)


and...
=we see no attempt to update cloud.35uu.cf. It's never even tried, so there's no error for us to go on... no logs available
Please delete the root record in the router, and disable the "Use multiple hosts" option, and just set cloud.35uu.cf to see if it updates. Then re-enable the multiple hosts, and add the root.

OK this sounds like my router must be firing off both requests separately and too close together and a firewall (at your end? or somewhere between us?) is ratelimiting or something (which seems odd for 2 requests, when most rate limiters default to >=3 requests within a minute), because my router is claiming the request is failing with a server error. By doing what you suggest there, the IP for cloud. will update on the next 30min mark but then adding the root domain after it will just end up with the same problem in reverse, cloud. will update but @ will not.

Hey, sorry to resurrect a necropost...

Yep, I did as suggested; and just as I expected, now cloud.35uu.cf is 1st in the list, it updates, anything else I add to the list does not and the router logs still say it's a server error and retries every half an hour, but last time you looked you said you only saw the first successful request, and no subsequent server error.

current list:
cloud.35uu.cf
thelab.35uu.cf
35uu.cf

If you're not seeing the requests and I can't see any detail on why the router thinks it's a server error, I can't see how we can debug this.

I tried calling my ISP to find out how to report a bug in the router's ddns client/config page, but they said they don't have any way for me to do that and forwarded me to a 'tech experts' team who had no idea what I was talking about and tried to tell me that I don't have a dynamic IP and only business users need to buy DDNS (which is backwards, only business users can buy static IPs, and DDNS is not a service they even provide to sell to us, the router page only has config for free-for-personal-load 3rd party services like yours). Needless to say, I gave up on trying to report the feature as broken.

our servers have the records for all three dynamic host at present.. did you do anything manually on the zoneedit management area? like add the IPs manually?

Yes occasionally I manually update the two that do not automatically update.

Last time was the day before I posted that last message

do all the host need to resolve at the same IP?

Yeah, that's what I've been saying heh...

Yep, that's why I update the other two manually occasionally.

Can you please let me know after the next ddns update has been attempted so I can check into some fresh logs.
