Hi all, unfortunately, this bug is not fixed. I updated all the packages built from qtbase to version 5.5.1+dfsg-8, and did a reboot - but the ownCloud client is still not reconnecting to the server after I switching from wired to wireless connection. I am unsure now whether this means that there's another bug in ownCloud, or whether maybe the bug in Qt has not really been fixed. Kind regards, Ralf
