Jenkins : Determining build queue position

There are 3 pull requests open for hammer-cli-foreman-discovery. There are two sets of tests running on each pr - default and hammer.

The weird thing is it looks like the last run was successful:
But Jenkins can’t determinate the state of the test queue according to the error.
It’s been that way from April 19th, I don’t know what’s changed.

Maybe this? Just a hunch.
