Attaching Rpi gets invalid checksum on initial d/load

I had to reimage and reinstalled a couple of Pi3's tonight.

Once I've got BOINC installed I add E@H which then downloads the various files it needs. In both cases tonight its thrown checksum mismatch errors on the NEON_Beta executable when attaching. All the other files download fine.

To fix I did a project reset and then allowed new work which re-downloaded the NEON_Beta app and is happy again. Below is the log from the first one I did tonight. Times are in UTC +10. The first host is computer #12282313 and the second host is #12262172.
