Jenkins GitHub plugin can't choose my credentials

I got very strange behavior that has never happened before, when I try to configure the GitHub server in Jenkins general configuration to set up webhooks auto.

The drop down menu doesn't display my registered credentials. I was always be able to do that, but suddenly I don't know what's happening. I tried to uninstall the plugin, restarting Jenkins, kill the Jenkins Docker container and configure all the stuff again ... still I got the same issue.

Enter image description here

There is no other option other than none, and when I add new credentials I still get None as the only option...

What happens when you click on the "Add" button? Have you tried adding other credentials? – Hubert Grzeskowiak
yes this is what I can't understand when I add new ones I still get none as the only option – ZEE
Github plugin only accepts plain text credentials (wiki.jenkins-ci.org/display/JENKINS/Plain+Credentials+Plugin). Have you created one manually or via the Advanced... options? – Hilborn
You can remove your token from github.com/settings/tokens and let the plugin generate a new one – Hilborn
I'm glad this solved your issue :) Haha I actually had this exact same problem yesterday when setting up the Github plugin in my Jenkins service – Hilborn

The issue is that the GitHub plugin only accepts plain text credentials.

The GitHub access token can be created manually, or automatically via the Advanced... options as described here.

In case you already have an access token in GitHub (you'll get an error in Jenkins), you can remove it in Github. Then you can let Jenkins generate the token and select it in the Credentials menu.
