HTTP Post Not Working

I followed the following blog - https://www.raviyp.com/embedded/194-sim900-gprs-http-at-commands?start=1

That website also changes to http://ptsv2.com/.

When I send the data to the server by AT+HTTPACTION=1 it shows the following error message.

+HTTPACTION: 1,400,29

My server - http://ptsv2.com/t/0q2uu-1572689933

My Post url - http://ptsv2.com/t/0q2uu-1572689933/post

I used following code,

AT+HTTPPARA=“URL”,“http://ptsv2.com/t/0q2uu-1572689933/post

AT+HTTPPARA=“CONTENT”," multipart/form-data; boundary=-------------------------acebdf13572468"

AT+HTTPDATA=270,10000

I used Arduino serial monitor.

Are you posting the data content after you get the “DOWNLOAD” message from the module and receive a “OK” after you send exactly 270 characters (as far as I can see you are sending a little less than 270 characters)?
