Application Links again

[charleslcso]

Hello, I am seeing an issue, and I'm not sure if it has something to do with Application Links.

First of all, Jira 8.20.0 -> Crowd 3.7.2 , Jenkins -> Jira 8.20.0 have been working.

A few days ago I did a minor upgrade to Jenkins, and at the same time migrated it to a new server. All Jenkins' jobs no longer run. I get a 401 in Jenkins when I Test Connection to Jira.

At the same time, Jira's atlassian-jira-security.log says my Jira ID tried to login but I do not have USE permission or weren't found.

In Jira, under User Management, Jira can connect to Crowd, and I can authenticate and log into Jira using my ID.

I checked Application Links in both Jira and Crowd. Jira to Crowd has Network Error (please see screen below), while Crowd to Jira is Connected!

What is going on? The OAuth version mismatch between Jira 8.20 and Crowd 3.7?

Nevermind, it is really a problem with reverse proxy configuration.
