Could not establish secure channel for SSL/TLS with authority '*'

Question

I must consume a PHP webservice which has a SSL certificate. My .net 3.5 Class library references the webservice with \'Add Service references\' in Visualstudio 2010 (WCF ri

Answer 1

Here is what fixed for me:

1) Make sure you are running Visual Studio as Administrator

2) Install and run winhttpcertcfg.exe to grant access

The command is similar to below: (enter your certificate subject and service name)

winhttpcertcfg -g -c LOCAL_MACHINE\MY -s "certificate subject" -a "NetworkService"
winhttpcertcfg -g -c LOCAL_MACHINE\MY -s "certificate subject" -a "LOCAL SERVICE"
winhttpcertcfg -g -c LOCAL_MACHINE\MY -s "certificate subject" -a "My Apps Service Account"
