Too many POST requests via PHP crashing site.

Hi, my site uses normal POST requests via PHP and if my users do too many it gives them 

error code err_empty_response and kicks them off for about a minute. 


I don't have this error anywhere else, even on free hosts I can send 100 requests no problem. 


Can someone help me with this please


Re: Too many POST requests via PHP crashing site.

When any sites show ERR_EMPTY_RESPONSE it happens most of the times due to dns issues. 

It is an easy fix. Although there are 5 more solutions but in my this will work. Just follow this solution to flush dns.


  • Go to Command Prompt by pressing windows key and X and select Command Prompt.
  • Now, just paste these commands one by one and after every command hit enter.
  • Commands: ipconfig /release

ipconfig /all

ipconfig /flushDNS

ipconfig /renew

netsh int ip set DNS

netsh winsock reset

Lastly, just reset your PC or the device and see if it makes any changes.
