Summary of the issue you are facing:

The issue I’m facing is that external users don’t seem to be able to log in. When I created the shares and then added e-mail addresses I never sent an e-mail to the users, and the external users aren’t able to log in. Users on our domain are. I rebooted, and immediately after reboot I was able to log in as an test external user, but no longer. It’s very strange and I am very much a noob when it comes to Nextcloud administration.
[…]

Steps to replicate it (hint: details matter!):

  1. Reboot
  2. After a little while the external users will not be able to log in.

Tips for increasing the likelihood of a response

  • Use the preformatted text formatting option in the editor for all log entries and configuration output.
  • If screenshots are useful, feel free to include them.
    • If possible, also include key error output in text form so it can be searched for.
  • Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
