Hi, Forget the backend id, it's the wrong answer to that problem. I was investigating an other potential issue, but this does not fix the original problem reported here.
Here is the answer I delivered today on discourse, where other people have also reported the same issue: Just to let you know that I think I found the cause of the issue but I don’t have a fix yet. I’ll come back to you this week with more info and hopefully a fix. The issue seem to be in srv_init_addr(), because srv->hostname is not set (null). Baptiste
