Hi I have implemented authorize.net  CIM  using SOAP service reference in asp.net (C#) and was  working  perfectly.

I am using developer service reference as - https://apitest.authorize.net/soap/v1/Service.asmx 

and sandbox account in live mode.

Today, I am receiving timeout error while creating payment profile. To resolve this issue I hit the service URL to see response of this service  in browser's window but it is taking so much time to load..

Please kindly help me to resolve the Issue.
