I'm trying to configure server-based integration between CRM Online and SharePoint 2013 on-premises and this is the error that shows up on the validation step:
Cannot contact site at the specified URL sharepoint.domain.com/.../crm
Is this because we're using a non-standard port (4443)? I can confirm that the SharePoint site is accessible from the internet through a reverse proxy (Microsoft Remote Access) and users can successfully log on via AD FS. We're using a 3rd party certificate.
I've gone through the steps mentioned here to grant Dynamics 365 access to SharePoint On-prem: https://technet.microsoft.com/en-us/library/dn894709.aspx
Anyone know what else I could be missing?
