Solution :

This is definitely the problem related to server. Probably the server is not following the HTTP specification and so the .NET client has flagging this as a potential problem. 

There is no security issue here but only non-compliance with the RFC. 

So to resolve the problem please apply the bellow configuration change:

<configuration> 
 <system.net> 
  <settings> 
   <httpWebRequest useUnsafeHeaderParsing="true" /> 
  </settings> 
 </system.net> 
</configuration>
