JENKINS-30284 fixed an issue where the EC2 plugin was too aggressive when trying to contact a slave that just got created. So in theory the version I'm running should try 20 times by default before aborting.
However, it still aborts after 5 quick attempts like the initial comment on JENKINS-30284.
I tried to run jenkins with -Djenkins.ec2.bootstrapAuthTries=20 but it seems like it's getting ignored.
If I then launch the slave agent manually everything works just fine.
Am I doing something wrong?
