Hello all,
It seems the RouterOS 7.xx dns-update command is no longer working with the ChangeIP dynamic DNS service, or at least I couldn't get it to work.
Based on some other suggestions here I have modified the "official" ChangeIP script. This modified method uses the fetch command to HTTPS/GET the DDNS API. I have verified on my account it shows as "Mikrotik/7.x Fetch" and updates successfully.
I'm not a RouterOS scripting guru, so any feedback is welcomed.
