Application links - creating incoming external link - We couldn't save your link

[Michał Ziemba]

I follow the article Confluence On-premises Microsoft Graph connector (preview) and I am stuck at the step 3.5 authentication type. If I want to use oAuth 2.0 and following the steps below: 

1. Go to Administration  > General configuration > Application links.
2. Select Create link
3. Select External application, and then choose Incoming as the direction.
4. Fill in the
   • Redirect URL: https://gcs.office.com/v1.0/admin/oauth/callback
   • Scope: Admin
5. Complete the connection settings step using the client ID and secret.

I also found similar guide at Confluence documentation: Configure an incoming link | Confluence Data Center 9.1 but when I try to save the link, I got an error (no matter what permission level I choose):

We couldn't save your link.
Fill in the required fields and try again. 

I have attached screenshot. I have no idea what extra fields it requires to be filled in as there is not much in the form and all is filled in. 

Do you have any suggestion how to overcome this obstacle?

Thanks in advance
Michal

Hi @Michał Ziemba 

Check the log file docs for the correct log file.

Hi @Michał Ziemba 

I'm not a systems admin.

But AS I look at your picture, you are connecting to your Confluence on localhost.

I do think to make this work you Confluence has to run over https as well, to make the secure callback.
