Error SymHelp

Hello,
I'm trying to use the SymHelp, Load Point Analysis feature, but I always have the following error message:
 

I've already set the proxy but it logs the proxy could see that he does not send authentication information already created permissions in my proxy for many addresses that the barring was due to lack of authentication, when the proxy is not barring any addresses he barred SymHelp when I was running, but the problem persists.
Can anyone give me any tips of what to do?

Thank you,

Arthur Sant'Ana Fernandes
