Same problem here, right now.
Even with "Prefer Secondary" checked.
Earlier in the day it was working without any issues.

Update: It's working again.

It started again .
I'll check it out tomorrow.

I will restart builder1. Looks like it needs it.

It worked for a while, but now the problem has returned.

Do you get this error with both builders now?
