How to troubleshoot Sabre Exception NotAuthenticated?

ℹ️ Support

I do not understand how am I supposed to troubleshoot this error, I am able to connect to NextCloud using the same username/password, but Sabre claims I am not authenticated when using it with the curl command. (it doesn’t say the user or password is invalid)

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

nextcloud.log is empty

Works for me. I can only generate the NotAuthenticated if I deliberately put the wrong password in. At least in NC27.
