An error occurred when I create issue in Confluence

[안우전]

I'm getting these errors from Confluence when trying to create issue. 

And click 'Allow access' I get this error

Authentication failed!

An error occurred while trying to obtain an access token. For application link 

OAuth Problem Details

• Failed to get token from service provider. Secret is missing in response. Response status code is '403'

I've already application link Confluence <-> Jira. but I think confluence to jira is not working normally.

Here is my application links setting

When I click 'Authenticate to see status', I got same error mentioned above.

What does this mean, and how do I fix it?

• Both Connections Local authentication Outgoing / Incoming is OAuth.
• Confluence and Jira is on Cloud.
• I set IP allowlisting for only using within the company

Thank you for your help!

@안우전  Hi,  Could you check application link on JIRA side ?

@Moses Thomas HI! 

Yes. Jira's application links status is 'connected'.

But I don't know what is working normally.

I've tried selecting link 'Find a Confluence page' on Jira's issue page and works well.
