Bad Request with 2 Fields on Arduino | Arduino | Forum

From Nick:

I’m getting a the following message when posting to more than one field:

HTTP/1.1 400 Bad Request
Server: nginx/0.8.53

…disconnected.

this is the line I’ve modified:

if(!client.connected() && (millis() – lastConnectionTime > updateInterval))
{
updateThingSpeak(“field1=” + analogPin0 + “&field2=” + analogPin1);
}

It works when I only use field 1. What’s the problem here?
