    SQL Developer connects extremely slow



      I have reviewed the other (archived) Thread dealing with probably the same issue.
      SQL Developer starts OK, the Splash screen has been disabled but opening up a connection
      to a Server (fast one), which sits behind a firewall and port 1521 being open, takes around 7 Minutes every time,
      after that SQL Developer behaves normal when executing scripts, importing/exporting data, etc.
      Any clue or hint where to look ? Any log files to look at ?
      Any additional Port that needs to be opened ?

      Version is 19.2 on 64 Bit Windows.
      Thanks for any help.
