I've been trying to set up a connection to MySQL from SQL Developer for several days now, but can't get past the above error. I've followed the instructions i.e. downloaded the latest .jar file from MySQL, saved on my laptop, and added and entry in the Third Party Drivers. I have the MySQL tab in my connections, but when I try to connect to my MySQL database (which is on a virtual linux machine in virtualbox) I get the following error:
Status : Failure -Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
I can ping the ip address for my VM from my laptop so not quite sure what's going wrong.
Has anybody else has this issue and resolved it successfully? If so I'd be grateful for some advice.
SQL Developer Version 4.1.5.21
MySQL version 5.6.32
MySQL JDBC Driver version 5.1.43
Oracle Linux 7
