Hi,
I have a FritzBox and i need to give up my static ip nr, i have my own DNS at a hosting provider, is it possible by using your code on a pi to update the dns with new dynamic ipnrs?

regards
Eelco

Is it possible to disable e.g. the polling strategy if I only want to use the pushing strategy?

Hey, why aren't there any issues, yet? Nobody using it am I just to stupid? :-(
I think I set the API token successfully, still the log states that the token is missing. Looking at the code this can only happen, when the token is not set.

Further you are writing in the description that the token should be set in the .env file. From what I understand the .env file only sets variables for the compose file, but does not reach the container: environment variables defined in the .env file are not automatically visible inside containers.
So I set the var in the environment: area of the compose-file, see below: no change

updater_1  | time="2020-11-24T19:45:18Z" level=info msg="Env CLOUDFLARE_API_TOKEN not found, disabling CloudFlare updates"

$ docker/cloudflare-dns-update$ docker exec -it cloudflare-dns-update_updater_1 sh -c 'echo $CLOUDFLARE_API_TOKEN'
y......................................_

What did I do wrong?

First of all, great project! This enhancement request should be pretty easy to implement.

For added resiliency, add a health check endpoint to validate that the updater is actually running.
Proposed endpoints could be /health or /alive, with a simple HTTP 200 as the response code. Maybe add an "ok" in the body.

Bonus points: A JSON response which lists if the last communication attempts to the Fritz!Box and Cloudflare were successful. Still keep the 200 response code, even if these connections were not successful.

Hi,
when I try to run the docker container I get an standard_init_linux.go:219: exec user process caused: exec format error. I used it one time with the environment variables for polling and one time for pushing but I get immediately this error.

Hi,
I was trying to set up your container as part of a compose (v 3.7) with the following config:

  dyndns:
    container_name: propaganda
    image: adrianrudnik/fritzbox-cloudflare-dyndns
    environment:
      - CLOUDFLARE_API_TOKEN=<API_TOKEN Redacted>
      - CLOUDFLARE_ZONES_IPV6=redacted.domain.com
      - DYNDNS_SERVER_BIND=:8081
      - DYNDNS_SERVER_USERNAME=<user>
      - DYNDNS_SERVER_PASSWORD=<redacted>
    labels:
      - traefik.enable=true
      - traefik.frontend.rule=Host:<redacted>
    networks:
      - srv

Running this results in the following error:

It seems like the environment variables are not recognized, is there a known workaround?

Is there a change within the Fritzbox TR64?

This Script stopped working for me.

I get the 404 Error Message from the Fritzbox but the log say:

time="2023-11-20T14:52:08Z" level=warning msg="Failed to poll WAN IPv4 from router" error="Post \"http://192.168.99.1:49000/igdupnp/control/WANIPConn1\": context deadline exceeded (Client.Timeout exceeded while awaiting headers)"

I recently had the problem that when restarting the FritzBox after the new IP was discovered, the API call still failed because the internet still wasn't online. Some retry might be good here or maybe some improvement in the polling / saving the last set IP.

Proxy crashes when calling http://localhost:41010/ip?v4=80.128.62.108&v6=2003:cc:7fff:1026:e228:6dff:fe68:3f04&prefix=2003:cc:7f10:1800::/56 if the DEVICE_LOCAL_ADDRESS_IPV6 is not set.

When the service updates the cloudflare dns record it resets the proxy status to false even when it was set to true manually before the update.

It would be great if it keeps the existing value or if it was a configurable setting.

Currently I have Failed to poll WAN IPv4 from router all over my logs since I only have a public IPv6.
