RequestReduce throws (400) Bad Request Error

[smartabbas]

We have implemented RequestReduce on one of our website (www.guitarplayer.com) and it's working awesome, client is very happy with the upgrade in site speed.

However we tried implementing the same on one of our other website (www.techlearning.com), when i went to dashboard, there were some items in the repository, and below there were some Recorded Faiures, which were like below:

I checked the configuration, and it's exactly same as been prescribed on requestreduce.org and also the one we implemented for (www.guitarplayer.com). I have also confirmed the User Account has read and write access to my root folder.

Can you please let me know what could be causing this.
