DAVx5 sync error after I modify a task: Couldn't unbind CustomCertService followed by a thread interruption

[Shun Feng]

Hi,

I am using DAVx5 2.5.3-ose to synchronize tasks on CalDAV. When I do some changes to a task and save it in OpenTask, DAVx5 fails to automatically synchronize the changes with some error debug output shown below. However, I can sync them manually in DAVx5 app by tapping on the “Synchronize” FAB.

Here is the verbose output recorded. Note that every failed synchronization is caused by a thread interruption on okio.Timeout.throwIfReached or at.bitfire.davdroid.syncadapter.SyncManager.abortIfCancelled, which may be caused by a Couldn't unbind CustomCertService exception occurred just before the interruption.

Hello,

1. Do you use a custom (or otherwise untrusted) certificate and
2. maybe have disabled DAVx5 notifications?

@rfc2822
I disabled this Xposed Module that disables SSL verification and pinning (https://github.com/ViRb3/TrustMeAlready) and rebooted, and the sync seemed to work again. Thanks for the reply!

@Shun-Feng Interesting, I have never heard of this module. Thanks for the update!
