Cannot contact SharePoint on-premises server

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?

    It is possible that the issue is the port number, as the configuration is not expecting that value.

    You should see if you can get this to work with port 443.

    I'd stay away from integrating Dynamics with SharePoint. I was never able to get the server side integration working since 2016 and Microsoft was never much help. The way documents are managed in SharePoint in my opinion is a mess and I don't see much interest from Microsoft in making this integration a simple and straight forward feature. I'd keep my documents in Dynamics only, it has a pretty decent doc management.

    We are using SSL with a 3rd party certificate. The URL in the error message mentions "https ://sharepoint.domain.com:4443/sites/crm" but the https:// got hidden in the post.

    We had that issue in the past. Per Microsoft, SharePoint must use SSL.
