I use MySQL connection via UniDAC with http tunneling. When I assign TCRSSLIOHandler to Connection.IOHandler and properly change HttpUrl to https It usually works.
But then after some time (1-15 minutes) disconnects and error occurs (during trying to edit dataset or run query).
Sample error log:
exception class : SocketException
exception message : Failed to connect to server script.
