[GitHub] [arrow] marsupialtail opened a new issue, #37708: Using FlightSQL with Grafana FlightSQL plugin

marsupialtail opened a new issue, #37708:
URL: https://github.com/apache/arrow/issues/37708

   ### Describe the bug, including details regarding any error messages, version, and platform.
   
   I tried to use FlightSQL example Docker here: https://voltrondata.com/resources/running-arrow-flight-server-querying-data-jdbc-adbc
   
   I can query the service from Python no problem.
   
   However when I am trying to set up connection with Grafana FLightSQL plugin, it doesn't work. It complains: 
   flightsql: rpc error: code = Unavailable desc = connection error: desc = "error reading server preface: EOF"
   
   Have you guys seen this problem before?
   
   ### Component(s)
   
   FlightRPC

   It seems that you can't use non TLS connection:
   https://github.com/voltrondata/flight-sql-server-example/blob/44e855558da76eefad2d75c133c9676cd3102ad0/src/flight_sql.cpp#L112
   
   Could you open an issue on https://github.com/voltrondata/flight-sql-server-example/issues not here because the source code is managed on the repository?

   seems like some SSL version issue on the server: E0913 20:22:38.153841801      51 ssl_transport_security.cc:1501]       Handshake failed with fatal error SSL_ERROR_SSL: error:0A00010B:SSL routines::wrong version number.
   Is there a way to run the server on http instead of https?
