Gateway Timeout for POST Request

Hi there, im getting Gateway Timeout faultstring with the following request often

As it seems, if the request is longer than 55 seconds, it gives this error and gives actual results if below 55 seconds.

90% of the time, the request takes longer than 55 seconds hence having the error.

What is there to do about this? 

Sincerely,

POST Request
