Office Online doesn't work on a specific Web Application RRS feed

  • Frage

  • Hello y'all,

    we are currently setting up a SharePoint 2019 environment in our company. Installation, configuration and connecting to the application server worked fine. The standard Web Application with HTTP works with office web. 

    Then we created a new web app with HTTPS. However Office Web Apps doesn't work here. We always get an error:


    The only things I can find in ULS Logs is "WopiFrame: OnLoad Succeeded with TargetUrl: " (leads me to the web preview with error"

    and: "WopiFrame: OnLoad Succeeded with TargetUrl" (same as above)

    I wonder why this doesn't work, the certificates are correctly bounded, WOPIZONE is internal-https (tried it too with external-https). I can reach the new web app with https from the office web server.

    Does anyone know how to fix this problem?
