We have a SharePoint on premise with the name portal.contoso.com then we publish it using IIS ARR reverse proxy. for the name of the external portal, we named it portal.pcino.fabrikam.com. we have configured URL Rewrite on the IIS ARR Reverse Proxy server and when we open the portal using the name portal.pcino.fabrikam.com a pop up appears to login, but after logging in an error message appears with the message (Sorry, something went wrong File Not Found)
.
is there any additional configuration that has to be done both from the IIS ARR side and the SharePoint side? please help and advice
