I am having a similar issue, though I am using kernel 4.15.0-39-generic on Xubuntu.

Conclusion

At my case:
I experiences those problems.
If the desktop-client has a latest version and the nextcloud-server stuck at version 13.
I installed a new nextcloud-server to version 17.1 and this issue, does not appear anymore.
