If you experience problems connecting to Pathfinder Server you can try the following endpoints for troubleshooting:
status endpoint: https://localhost:8087/api/v1.0/info/status
If you want to know if the server is working, you can call the status endpoint without authentication being required. If successful, it will return the following information: mobile database creation index status, mobile database creation index progress, server version and uptime
ping endpoint: https://localhost:8087/api/v1.0/info/status/ping
This is meant to check if authentication for a certain user is working correctly. Calling this endpoint with successful authentication will return the uptime of the server.
