Can you provide guidance on how to confirm that the credential can be used after I attached it to my Jenkins user account from my user name drop down like this:

That dropdown allowed me to add a new GitHub personal access token to my Jenkins server, but then I am unable to see it in other contexts.

Robert Schulze I can't do anything further on this without your answers to my questions.

Sorry for the delay. Here are the details:

When I configure the job without build authentication

I can select global credentials and also successfully build with them:

However, when I configure the job to run as my own user

and I want to use the credential from my user 

I am able to select it in the configuration screen but already an error appears (the password is absolutely correct, double-checked multiple times)

and when I try to run the job, it runs on error since the credentials cannot be retrieved 

Full console log:
