FAQ

Answers to frequently asked questions.

Why am I logged out every time the server restarts? #

By default, AppservR signs login sessions with a secret it generates fresh each time it starts, so every restart invalidates existing sessions. Set the APPSERVR_AUTH_SECRET environment variable to a fixed value to keep sessions valid across restarts. See Running in production →.

Can I deploy an app straight from a Git repository? #

Not yet. The admin UI has a “Git repository” option in the app source picker, but it’s disabled and marked “not available yet” — only a local or network directory works today. See Configure your first app →.

What platforms does AppservR run on? #

Prebuilt binaries are published for Windows (32 and 64-bit) and Linux (64-bit). There’s no macOS build.

My app isn’t showing up, or seems stuck. Where do I look? #

Each app’s own page in the admin interface (/admin/apps/<name>) shows the console output of its running R workers. A worker that started successfully prints a “Listening on” line; anything else printed there (an R error, a missing package) is usually the actual cause. See Configure your first app →.

Can several apps run on the same server? #

Yes. Each app gets its own path, and paths can be nested (/ and /sales-dashboard and /sales-dashboard/internal can all coexist). Each app also runs its own R worker processes, independent from every other app’s.

How do I move AppservR to a new server, or back it up? #

Back up config.yml and the SQLite database file next to the executable, plus whichever directories your apps' source code lives in. See Running in production →.
