Malformed event blocks synchronization of other events

[haansn08]

I have an calendar event which causes a "HTTP server error - HTTP 400 bad request" on synchronization (HTTP PUT) which I am quite sure is a problem of the mailbox.org server not supporting some feature (but also no way to figure out which feature). This should however not block the synchronization of new calendar entries. I have created another (good) calendar entry in Evolution with important reminders, which does not show up on my phone at all, because of an unrelated bad entry.

I'm not sure if this is relevant or not. I also use mailbox.org and they have been having carddav and CALDAV server sync issues of recent. The have been a few notices on the front page of the webpage.

For example, yesterday was one such incident with carddav not syncing. Actually, as I write this I am unable to get calendars and tasks to sync for me. So my suspicion is it's a problem on the mailbox.org side and likely not with DAVx5.

I just tested synchronization with Evolution and it works fine, so temporary server problems are likely not the issue anymore.

I just tried again and calendars and tasks are now syncing for me as well.

Not sure what is causing the errors. Have you tried reaching out at mailbox?

[haansn08]

The problem is not the error itself, the problem is that synchronization of unrelated calendar events does not take place.

I have the same problem with mailbox.org just recently on two different calenders on the same login. DAVx4.4.0.1-ose on GrapheneOS. How di I find out which calender entry causes this issue and how to resolve it?

Hi, you can take a look at our "How to debug DAVx⁵-related problems" page.
