I can't edit the pipeline from blueocean plugin.

This is new instllation env.

in the browser I can see a blank output shows a window with title "connect to git".

But it show nothing more.

and Iook at the F12 network tool from browser, it shows a error 428 for the following link.

https://10.9.65.199/jenkins/blue/rest/organizations/jenkins/pipelines/devopsdemo-ctbri/scm/content?path=Jenkinsfile&branch=master

{
"message" : "Invalid credential",
"code" : 428,
"errors" : [ ]
}

see 2.png

and I tried to connect the link directly it got the same result.

I tried a shorter link, and here's the result:

https://10.9.65.199/jenkins/blue/rest/organizations/jenkins/pipelines/devopsdemo-ctbri/

Please help find where's the issue.

Thanks.
