Couldn't parse iCalendar

[ro-i]

Hi :) I use icsx5 to sync a calendar to a phone using an iCal link. This always worked flawlessly until yesterday, when I got the error message "Couldn't parse iCalendar". See below for the details. Does anyone have an idea of why this could have happened?

Hey there. Hard to know without the actual ics file. Can you provide a link or the contents of the file you are experiencing this with?

Hi,

I have the same problem on Android 14 with an iCal Link that is created by the Allris Webapp (https://www.cc-egov.de/allris). I can provide the Link to an developer.

You can use this support form or send the ics file to [email protected]. Please mention and link back this discussion as well

I have the same Problem in Android . But sorry i dont want to share the private ics File.

PS: in nextcloud the import of the same calender was No Problem.

Things work very differently on Android than on a PHP based server.

Couldn't parse iCalendar is such a generic message, it could be thousands of different problems... if you can't share any details with us we can't analyze it and it won't even get a chance to get fixed.
