No error reporting if login error

[arkanovicz]

Hi all.

My group mapping was not properly configured. I had to resort to xdebug to find the problem. The following exception:

throw new LoginException($this->l->t('Your user group is not allowed to login, please contact support'))

from lib/Service/ProviderService.php:448 is never shown on the screen, all we get is a blank 404 page.

Is there any way to enhance this error reporting?

Also, this specific exception wasn't displayed either in the web server error log.

What version of nextcloud do you use ? How your 404 is looks ? Normally LoginException is displayed as error on login page.

Sorry, I meant 401. Nextcloud 21.0.9.

Yep, status code is 401. But user must see the error like this.

Probably you have misconfigured reverse proxy that show empty page on status 401.
