Mobile app setup

The best way to access the ebook library is via the OPDS server, which some ebook apps have. The best option is Moon+ Reader or Maple ReaderSE (Android/iOS) on Android or iOS respectively. They are not free apps, but they have ad-supported versions.

Regardless of which app you choose, the setup should be the same. In the app, add a new OPDS server. The server URL should be https://calibre.mumquhar.com/opds, and the login credentials you were given should work.

If logging in does not work, do not keep trying. There is a Fail2Ban protocol running on the server that monitors logs for multiple failed attempts and bans the IP they come from.
