      Description

      Expected to happen:
      When connecting to a server with multiple entries in the SRV record, one should be picked first. If the connection to said hostname fails, another should be tried until a successful connection has been made.
       
      Actually happened:
      If the connection to the first entry picked fails, no attempts are made to connect to the other entries.
       
      Steps to Reproduce:
      Set up two servers and an SRV record for _minecraft._tcp.example.com

      10 0 25565 main.example.com
      20 0 25565 backup.example.com

       
      Kill the server at main.example.com.
       
      Connect to example.com with minecraft.
       
      Observe as the connection fails, and no attempt is made to connect to the backup server.
