could not connect jira to Confluence

[Mydesq Support]

Dear Team,

We are trying to setup Application link between Jira ServiceDesk and Confluence.
While Setting up the application link, we are getting the following error message:

Invalid OAuth Signature
We could not connect to Confluence, possibly because that instance is behind a misconfigured proxy

Settings which I have done on both the sides:

-> Outgoing and Incoming connections used as Oauth (Impersonation) on both the side.
-> Enter the Application URL with external IP address

Could you please suggest the solution asap?
It would be really appreciative?

Thanks

Hi @Mydesq Support , 

the message you're seeing :

We could not connect to Confluence, possibly because that instance is behind a misconfigured proxy

means that there is a problem with the network between both instances. You should have a look at the documentation to debug this : https://confluence.atlassian.com/kb/network-and-connectivity-troubleshooting-guide-720405335.html
