Dolphin - webdav files copying gets stuck

Hello.
Copying process to webdav storage gets stuck with files larger than few megabytes.
This is journalctl log with successefull copying of small (few kilobytes) file:

plasmashell[1208]: New URI "file:///home/popombo" "" ""
plasmashell[1208]: New URI "webdavs://popombo@webdav.yandex.ru/bin" "" ""
plasmashell[1208]: file:///usr/share/plasma/plasmoids/org.kde.plasma.notifications/contents/ui/NotificationPopup.qml:116:15: QML QQuickItem: Binding loop detected for property "height"

I just don’t know why it is not copying. Popup keeps hanging showing 100% and file does not appear in webdav directory.

I had an old laptop, where everything worked fine, but it died last week. On this backup laptop it stucks. What am I missing? Or what settings might changed in newer Manjaro installations? Old laptop was with Manjaro installed 5-6 years ago, but upgraded to latest packages(of last week)
