I am currently attempting to create a binding between my SharePoint environment and our Office Web Apps server.
I am able to connect to the Office Web Apps server when I allow HTTP connections (on both the Web Apps Server and the SharePoint server) and create the binding using the -AllowHTTP command but am unable to connect to the server when trying over HTTPS.
I have created a DigiCert UCC certificate for the Office Web Apps server that uses the common name of the DNS CNAME entry for the Office Web Apps server (owas.contoso.com) and includes the FQDN of the server in the SAN (saowas.contoso.local).
I can ping the Office Web Apps server from the SharePoint server and can hit https://owas.contoso.com/hosting/discovery over HTTPS from the SharePoint server, and have disabled the firewalls on both servers.
When I attempt to run New-SPWOPIBinding -Servername "owas.contoso.com"on the SharePoint server it quickly gives me the WARNING: The server did not respond. Trying again (attempt 1 of 5)errors.
Any help would be appreciated.
