I am using the nextcloud calendar app with Five different calendars. Four of them work just fine but one of them “studies” creates trouble:
- In the nextcloud itself, when I change the month, this specific calendar takes like 10 seconds to load the events.
- When I want to “Download” the calendar “studies”, it brings me to:
This page isn’t working - blabla.net is currently unable to handle this request. HTTP ERROR 500
- I use Thunderbird/Lightning through CalDav to have my calendars on my computer. This synchronizes all other calendars but for this one calendar I get an explanation mark and don’t see any events. The Thunderbird Debug Log states:
CalDAV: Error doing webdav sync: 500
Lightning:“There has been an error reading data for calendar: studies. However, this error is believed to be minor, so the program will attempt to continue. Error code: DAV_REPORT_ERROR. Description: There has been an error reading data for calendar: https://blabla.net/nextcloud/remote.php/dav/calendars/blabla/studies/. It has been disabled until it is safe to use it.”
Lightning:There has been an error reading data for calendar: studies. However, this error is believed to be minor, so the program will attempt to continue. Error code: READ_FAILED. Description:
Lightning:[calCachedCalendar] replay action failed: null, uri=https://blabla.net/nextcloud/remote.php/dav/calendars/blabla/studies/, result=2147500037, operation=[xpconnect wrapped calIOperation]
A surprising thing is that the sync with the Gnome Calendar (using Gnome Accounts for Nextcloud) seems to work fine. (Can create events and syncs fine.)
CardDav for my contacts also works fine.
From what I found in other threads I could speculate that in this calendar some entry might have an invalid entry and that messes up the whole calendar. But I wouldn’t know which entry that is or how to find it.
Other reasons I don’t know.
Any ideas are highly appreciated.
