Not sure if this is a bug, but at least kind of annoying, thus starting here. Since client version 5.x on Windows 10, I see the sync status quickly toggling between “Ready” and “Preparing to sync”. It seems at least sync itself still works, but with logging enabled it produces tons of log messages.
Do you host ownCloud server 10.13 in subfolder? like
domain.com/owncloud/ ? Then it might be fixed in the upcoming desktop 5.2 version. You can already test-drive with the RC:
Thanks a lot for the quick response. Indeed, this solved the issue.
