Steps to reproduce the bug

I noticed that my calendar in Thunderbird didn't included the events that I had been adding to visit in my phone. I noticed the http 400 error on DAVx5 reach time I tried to synch. I eviewed the phone settings which were as recommended.

I use mailbox calendar as a strategy to synch fossify to Thunderbird.

Expected behavior

Events created in fossify would show in mailbox calendar and Thunderbird.

Actual behavior

Events don't show in Thunderbird nor mailbox calendar.

What CalDav server are you using? Do you have access to server error logs?

Hi, In mailbox site they say it is this one https://dav.mailbox.org/caldav/folder-ID

But I can't open that link for some reason.

Hi @chesio Any news concerning this issue? Anything I could do?

Hello, I was investigating a similar issue on my side, and to me this is caused when an occurence of a recurring event is modified. DavX has an information page about it, which seems to indicate that the app may not properly match the icalendar standard when registering such exception https://www.davx5.com/faq/recurring-events There is a very similar issue in the simple calendar github which was solved about a year ago https://github.com/SimpleMobileTools/Simple-Calendar/issues/1538 and the cause may be similar (non unique ID for the exception event). Hopefully this can be solved.

I have no idea how to solve it. It's mostly gibberish to me. Maybe I can use a different synch app. Any advises?

I recently had the same error with DAVx⁵. It turned out that removing the account from it, then re-adding it with "Login via E-mail" instead of username, solved it for me. Maybe that works for you.
