OpenWrt Version

OpenWrt Target/Subtarget

mediatek/filogic

Steps to Reproduce

1- configure ddns-scripts no-ip client.
2- don't install wget-ssl or curl
3- ddns-scripts will use uclient-fetch and no-ip will reply with nochg even when a change is needed.
4- install curl. set ddns-scripts to use curl. same error happens.
5- remove curl and install wget-ssl. no-ip is updated correctly.

Actual Behaviour

update should work with either uclient-fetch or curl.

no-ip support says badly formated string is being sent. but they didn't provide the wrong string.
