Ways to solve 601 error in SIM900

Hey everyone,
I am trying to send some data manually to web server through POST method using gsm SIM900. As output i am getting everything fine but after the command AT+HTTPACTION=1
i am getting 601 error as a reply. I have searched a lot, still did not get correct output…

Can anyone explain me how to overcome this? Thanks in advance.
