Dynamics 365 AD FS issue

[DzoITadmin]

I'm having problem with Dynamics 365 version 8.2.6.19.

Not possible to connect to CRM via https. Also is not possible to use CRM outlook add-on.

I have used self signed wildcard certificate for AD FS, and got this warnings during installation.

When I try to add https://auth.contoso.com/federationmetadata/2007-06/federationmetadata.xml to Relying Party Trust, I get this error

Just to mention, I had this working before, I was able to connect, but since that I updated to this update, and it was not working anymore. Therefore I reinstalled ADFS service, but this seems like a bad step. 

If anyone understands this, and willing to help, I will gladly provide more details.

I sincerelly appreciate your assistance!
