Office Web - wrong URL

Question

Hello everyone,
I getting some error messages from my Office Web App server showing that is being accessed trough the wrong URL. I setup the server to be accessed trough HTTPS for internal and external trough
the same public domain. However there is still something making the server being accessed trough the FQN instead trough my public domain name. I also have my public domain name pointing to my Office Web App server on the DNS server. I'm able to open documents
using Office Web on SharePoint without any problem in most of the workstation. However at least one computer is giving me an error when I try to open a document from Office Web App, "run into a problem".
Below is how I setup Sharepoint 2013 and my Office Web App 2013 and the error log:
Thanks
Office web server:
New-OfficeWebAppsFarm –InternalUrl “https://app.contosco.com” -ExternalUrl https://app.contosco.com –CertificateName
"app.contosco.com" –EditingEnabled
Sharepoint server:
New-SPWOPIBinding –ServerName "app.contosco.com"​

Hi,
According to your description, my understanding is that the Office Web Apps cannot render the documents.
The error message is very common, please check the Event Viewer and ULS log to get a detailed error description.
Here is a similar issue link for you to take a look:
