Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud version (eg, 12.0.2): 14.04
Operating system and version (eg, Ubuntu 17.04): 16.04
Apache or nginx version (eg, Apache 2.4.25): nginx 1.14.2
PHP version (eg, 7.1):7.0

The issue you are facing:
User with Windows 10 cannot login to NextCloud on my server (Vultr).
I can login on my smartphone and Linux notebook.

Windows 10 is installed on a DELL laptop purchased in China. It is not possible to change the system language to anything but Chinese. User was sitting next to me and using the same wifi network when this problem happened.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Create a new user
  2. Send new user email share
  3. New user clicks on link (Nextcloud already installed)
  4. New user types in correct name and password
  5. Admin log immediately shows failed login.

The output of your Nextcloud log in Admin > Logging:

Warning	core	Login failed: 'Wendy' (Remote IP: '1.x.x.x')
