DDNS and Cloudfront

Hello :wave:

I have cloudfront working properly it seems using DDNS, however I keep on seeing this error message in my logs and I'm not sure why:

141408 WARN : Updating IP at DDNS provider failed - starting retry 174/0

That counter just keeps on increasing.. not sure why as it seems the update is being done.

This is my DDNS config:

config service 'cloudflare'
        option service_name 'cloudflare.com-v4'
        option use_ipv6 '0'
        option enabled '1'
        option lookup_host 'hostname.MyDomainOnCloudflare.com'
        option use_syslog '2'
        option check_unit 'minutes'
        option force_unit 'minutes'
        option retry_unit 'seconds'
        option domain 'hostname@MyDomainOnCloudflare.com'
        option username 'myEmail@myemailprovider.com'
        option password '***************************'
        option use_https '1'
        option cacert '/etc/ssl/certs'
        option dns_server ''
        option interface 'wan'
        option ip_source 'web'
        option ip_url 'https://ipv4.wtfismyip.com/text'

any ideas?

Nobody has had this issue before?
DDNS appears to be functioning properly, however I keep on seeing rust error message. :thinking:

Are there any details?

nope it's empty. :frowning:

I've compared my settings with other ppl who use this service and I can't see anything that could be causing this error..

The only thing I see is when it checks to see if an update is required.. it "thinks" the IP is wrong since at the last update the DNS entry was updated to 1 of CF's proxy servers.. and not the actual WAN IP I have assigned.

I have just run in to this issue as well. I think it is because the script updates your IP with Cloudflare (which is successful) but then checks the DNS again for your domain to see if it worked. Since it is being proxied via Cloudflare, the DNS does not actually match (nslookup your domain will give you one of Cloudflare's IPs which then proxies requests to your actual IP) so the script thinks it failed.
