If I interpret the messages correctly the app has problems to interpret a time stamp in a calendar record. You should open the relevant entry by opening the “REMOTE RESOURCE” link on top of the debug output. This should help ypu identifying which record is causing the problem and how the time stamps look like.

Thanks. I deleted this event. but this error messages come again for other events too after it.

i installed the previous version 2.2.3.1 and now it works again. so i deactivated now the updates. its a bug in the newest version of davx5.

Hello,
@hell said in Error Message:
its a bug in the newest version of davx5.
If it would be that easy… seems to be a variation of https://www.davx5.com/faq/java-lang-nullpointerexception-java-util-gettimezone. So: does it work if you now install DAVx⁵ 2.3 again?
-
Wouldn’t it be helpful to see how the original date/time string looks like which causes the problem or is the root cause defintely confirmed?

i will try later to install again the newest version and will post here the result. yesterday i tried to remove my caldav/carddav accounts and installed them again. this didnt help. same error messages. if it doesnt work with the newest version of davx5, i can’t check every event. i have thousands of events in my calendar. Editing/correcting every event is not an option.

That won’t help in this case. You will have to re-install DAVx⁵ (for unknown reasons).
