Calendar synchronization failed (404 not found)

[qirtaiba]

I am using Radicale 1.1.1+v14 on Sandstorm with the Android app OpenSync as my client. I'm not sure whether the error that I'm getting is due to OpenSync or Radicale. On my client I get this:

Calendar synchronization failed - Server error while downloading remote entries

This began only suddenly, so I think it's associated with some particular calendar entries that I must have added recently. I turned on logging in OpenSync and this file is what I got.

Any suggestions for how I can fix this error—or should I just ignore it?

I'm not sure why davdroid requests /radicale/owner/calendar.ics/owner/calendar.ics/America/New_York.

My only theory is that America/New_York is a file inside radicale's data directory. You could try deleting it manually.

At this point I'm not using Radicale or Sandstorm myself (and very few people did anyway), and unfortunately cannot dedicate time for support.
