Direct Database Connection through SSH tunnel

Win10 Pro, new intall of Wappler
Remote target set and made active
Remote target access via SSH successful
Move to setup Direct DB Conn
enter in all verified credentials, ports etc.
Test results in:

“Error connecting: Knex; Timeout acquiring a connection. The pool is probably full. Are you missing a .transacting(trx) call?”

Have tried with firewall exceptions and firewall turned completely off with no change in result.
I am able to use my other regular tools like mySql Workbench as expected.

Thanks for reading, any suggestions before I go back to Drumbeat 2000?
