Custom IPv4 DDNS update (Dynu) failing "Malformed input to a URL function"

[jhg]

Here's the log extract, what I need to know is whether this error originates in pfSense or Dynu's API. Log entries are in reverse time order (most recent first):

@jhg
Which URL pfSense is sending is shown in the log.
Request Dynu for the correct format.

You can also check the URL with curl in the shell or in a web browser.

@viragomann I figured out the problem. The URL entered in the DDNS configuration page had a leading blank due to being copy-pasted from the Dynu web page.

Enhancement suggestions:

• Remove leading/trailing spaces from the URL before building the curl command.
• Provide better error messages, and an option to enable verbose logging from the curl command
