<p class="MsoNormal">What happens if you run the daemon in foreground / high verbosity ? Paste error logs back here. My guess would be there is some kind of blocking happening, ie DNS lookup possibly try using an alternate resolver ?<br>

<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">The indicated error number (28) seems to suggest a timeout is occurring with curl, however examining a capture of network traffic when this happens shows that a http request is not sent from the server to the destination at all, usually
attempting a second call results in everything working correctly.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">As stated its intermittent in its nature and so I cannot reliably trigger this issue, other than through sheer repetition, so any ideas as to what could be causing this issue would be gratefully received,<o:p></o:p></p>
