Communications link failure | - MySQL
Over the last few months, I have been getting a Communications link failure message whenver I try to do anything to a mysql database in DataGrip.
When I test the connection, everything appears fine but refreshing the tables, trying to insert data etc all end with this message.
Communications link failure. The last packet successfully received from the server was 28 milliseconds ago. The last packet sent successfully to the server was 28 milliseconds ago. and 11 duplicate reports
Appreciate the vagueness of the above but is this a datagrip issue? It was working fine until a few months ago.

You can check for solutions in this thread. I should have noticed that this error was mostly happening during database connectivity, whereas in your case, the error is generated when introspection is triggered. We also had a similar report but without any feedback from the client. So I'd suggest to check the solutions provided in the thread first.

Nharriman , could you elaborate and provide more details?
What has changed in your environment?
In general, the error says that one can't connect to server and in the tree (database explorer) one can see only cache (offline) schema.
