Status: UNCONFIRMED

(Calendar :: General, defect)

Attachment: console-export-2023-2-5_10-32-50.txt

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:105.0) Gecko/20100101 Firefox/105.0

Steps to reproduce:

Have an existing calendar online at provider t-online. Updating of single dates to and from TB works perfect via WebCal Without TbSync and any provider.
Calender URL:
https://spica.t-online.de/spica-calendar/caldav/principals/[e-mail]/calendars/USER_CALENDAR-17458214/

I try to import a .ics file with the import assistant of TB.

Actual results:

TB starts importing, but stays at 0% forever

Expected results:

The dates in the .ics file should appear in TB

Addendum:
Importing to a local calendar works.
Tried also with a minimal ics-file exported from TB:
