I installed Sitecore 9, but I'm facing an issue with xConnect I tried to Open the web https://xp0.xconnect and I see an error
HTTP Error 403.16 - Forbidden Your client certificate is either not trusted or is invalid.
Module IIS Web Core Notification BeginRequest Handler
ExtensionlessUrlHandler-Integrated-4.0 Error Code 0x800b0109
I used the Chris Auer installation guide, which is excellent and it also generates the Certificate as well.
On the Server Certificates, I can see the generated Certificates. I also tried to generate and Self Signed Certificated and Change, but all my attempts failed Any suggestions? thanks
