Hi

I have a Raspberry Pi, which is used to collect my BOINC statistics of tasks. Recently I deleted its computer record in computer list of Milkyway@home. (it’s arm32v7 arch which never run any MW@h tasks)

Now I use boinccmd —project_attach to re-register this tiny Pi, but it never succeeded.

Does anyone know what’s going on here about the re project-attach for an once-existed, but deleted client?

thanks for any clues

You are mistaken. There never has been any application for the ARM architecture at this project.
You must be thinking of a different project where they support ARM architecture.

I found it is the fault of milkyway@home now (not bothered by arm-based client of Pi to access/register as a new client)
I tried to register another client on x86-64 based Windows 10, and it also failed

Keep banging on Milkyways door, ie keep trying, and it should go thru at some point, I'm seeing this at alot of projects, Einstein and Milkyway and even NFS, lately and banging on the door seems to make the Server wake up and connect
