Service unavailable

The ERP engine did not start

The site is up, but everything backed by ERP data is unavailable until the engine can reach its database. Signing in will not help — this is a server-side configuration issue.

Down
ERP engine Database, schema and posting engine.
Up
Identity provider Sign-in and registration.

What to check

  1. Is the database running? For local development that is SQL Server LocalDB. Start it, then restart the site.
  2. Is the connection string right? ConnectionStrings:Default in appsettings — check the server name, database name and credentials.
  3. Can this host reach the server? Firewall rules and named-instance resolution are the usual culprits on a remote SQL Server.
  4. Does the database exist? The engine creates the schema, not the database itself. Create an empty database first.

The engine boots once at startup, so restart the site after fixing the cause. The identity provider is re-checked automatically.
