An app tile gives 404, or "untrusted domain"

What you see: clicking Tasks, Calendar or another tile on the Overview opens a plain "Not Found" page, or LosOS cloud shows "Access through untrusted domain".

"Not Found" from an app tile​

Two causes, both fixed on 6 October 2026 (pull requests #65 and #66), both brought by the nightly update:

  • The tiles linked to the short /nextcloud/apps/<app>/ form, which LosOS cloud's web server did not answer in the default app mode. The tiles now go through /nextcloud/index.php/apps/<app>/, which every configuration answers.
  • The app itself is not installed or is disabled in LosOS cloud. Open LosOS cloud → Apps and enable it.

Until the update lands, open LosOS cloud from the Files tile (or /nextcloud) and use its own app menu, which generates working links.

"Access through untrusted domain"​

LosOS cloud only answers to names it trusts. The box tells it, per request, which address the request arrived on, so both <name>.local and the IP address work, and never a wildcard. You see this page when:

  • you reached the box by a name that is not its own: an alias from your router, a hosts-file entry under another name, or a domain through an edge that the box was not told about. Use <name>.local or the address.
  • the box's name was changed a moment ago and LosOS cloud has not been restarted yet. Wait for the rebuild to finish.
  • a box from before 6 October 2026, reached by IP address: pull request #65 added the per-request trust. Use <name>.local until the update.

LosOS Git prints clone URLs with the box's .local name even when you reached it by address. The pages work either way; for git clone, substitute the address, or add the name to your hosts file (The name does not resolve).
