"No connection" after reboot Linux Mint & Windows 10

Hey guys,
I have a little big problem with a nextcloud server. I can set up the client without any problems and it will run fine. Everything is working, sync with the server, upload files … but after a reboot (PC Windows 10 / Notebook Linux Mint) the nextcloud client can’t connect to the server. The only working solution is to delete the user from the client and create the connection as new. (no changes on the server) After that it is the same, everything works well until the computer reboots.

I would be grateful for help and ideas. Unfortunately, I am at the server only user and can make no changes there.

thanks, saigo

@jospoortvliet is there anybody from the NC team who can give more details? If not, you need to reproduce this with the original OC client (also works with NC servers), or you connect it to the demo server of owncloud on demo.owncloud.org. Then, you can report the issue to their bug tracker on github.com/owncloud/client/issues

Yeah, I think reporting at oC is the best course of action for now…
