Java Fehler beim Sync auf WebDAV Laufwerk (nur per Log Datei erkennbar)

Geschrieben wird eine "temp" Datei, aber das überschreiben scheint nicht zu klappen.

Can you reproduce this now everytime you try to make a change to the database?

Do you get any errors/warnings indicating that the remote file is broken (EOF sounds a bit like reading it isn't successful)?

Can you reproduce this now everytime you try to make a change to the database?

Yes. Auto and manual sync reproduces an error. Big red screen für a half second. Log gives a code 400

@Gothico74 Unfortunately I cannot access the file. It says it's in a private paste. You can also share it to [email protected]. Credentials shouldn't be part of log files, of course. I will fix this as soon as I see where exactly this is leaked.
