WOPI Service Unavailable

Question

I created WOPI host page .NET Core web app and WOPI handler .NET Core web api app. I tested everything with .wopitest file and it works fine. But when I switched to work with .docx, .xlsx etc I see error Service Unavailable We are currently experiencing technical difficulties. Please try again later.

Discovery XML url: https://ffc-onenote.officeapps.live.com/hosting/discovery

and I tried https://onenote.officeapps.live.com/hosting/discovery

How can I resolve this? Maybe I can debug/log it somehow?

Answer 1

The issue was in my url:

wopi/{param}/files/{id} I thought it starts with "wopi" and in the end "/files/{id}"

but right url:

wopi/{param}/wopi/files/{id}

So as I understood required url: .../wopi/files/{id} or .../wopi_{something}/files/{id}

The documentation below seems a bit confusing.
