 `Test Connection` is disabled until you are authenticated and have either selected a discovered server or enabled manual override with saved settings.

+Maintainerr only lists Plex servers that publish a **reachable** connection to plex.tv. If authentication succeeds but the server dropdown stays empty, Plex is most likely publishing only a `local` connection that Maintainerr (running elsewhere) cannot use. This is common when Plex runs on a **VPS / cloud host** or behind unusual networking, where Plex's automatic Remote Access cannot detect a public connection.
+
+Fix it on the Plex side by publishing a reachable address:
+
+1. In Plex Web, open `Settings → (your server) → Network` and click **Show Advanced** (top-right) to reveal `Custom server access URLs`.
+2. Into that comma-separated field, add a reachable **HTTPS** URL — e.g. your server's `*.plex.direct` address: `https://<dashed-public-ip>.<hash>.plex.direct:32400`. The `.plex.direct` host keeps a valid certificate (a reverse-proxied domain with its own cert works too). Including the port is recommended; otherwise Plex falls back to your Remote Access port. You can usually copy the correct address from Seerr if it's connected to the same Plex server.
+3. Save and restart Plex. On some Docker images this setting is an environment variable instead — e.g. `PLEX_ADVERTISE_URL` on the hotio image — in which case set it there (the in-app field is managed by that variable).
+
+Back in Maintainerr, press the **Refresh icon** next to the server selector — the server now appears in the list.
+
+:::tip
+If Maintainerr and Plex share a Docker network, you can instead skip discovery and point Maintainerr at Plex's **internal** address (e.g. `http://plex:32400`) with manual connection override below.
