Hi - if the port is not open they shouldn’t be connected at all correct ?

The problem is that the issue happening intermittently and goes fine with
the restart -

Thanks
Bhavani.

Are you able to telnet to <public IP>  <db_port#>  from your local box?

If not ask network people to open the port on that <public IP>

Thanks
