📱 Desktop & mobile clients 💻 Desktop
1

Nextcloud version: 19.0.1
Operating system and version: Freenas-11.3-U3.2 jail version 13.3-RELEASE-p11
Apache or nginx version: Apache Apache/2.4.43 (FreeBSD)
PHP version: 7.4.8 (cli)

The issue you are facing:
Desktop client does not accept authentication after clicking Grant in the webui.

Is this the first time you’ve seen this error? Y
Logging in worked before upgrading to 19.0.1, admittedly on an ubuntu 18.04 environment.

Steps to replicate it:

  1. Start Desktop client
  2. Click Account | Log in
  3. Wait for browser login page to open,
  4. Click Log in, enter credentials
  5. Click Grant.
  6. Instead of logging on, the desktop client displays
