If you added private networking after your droplet was created, you have to enable it manually:

This fixed my issue.

Hello @alexdo , yes I have double checked. I have even deleted the managed db and recreated it. I have also spun up a new droplet temporarily in the same region with just mysql/mariadb on it, and still cannot connect via private credentials, but public works.

@daveprezzo @alexdo I have the same problem with MySQL Managed DB Cluster
With public connection everything works great, but when im trying switch into private connection have a timeout error:

PDOException: SQLSTATE[HY000] [2002] Connection timed out

Same problem here with MySQL Managed DB Cluster

Same here - I’m getting timeouts when connecting.

Same issue. MySQL managed DB in same region and Droplet has been added as a trusted source. External connection works via mysqlsh.

I’ve added the DB server port to cloud firewall, and allowed connections out on that port in UFW.

I attempted to disable restrictions by removing all entries from Trusted Sources, no dice.

We’re working on migrating all of our sites from Google Cloud Platform but this is holding up the process.

Just to test- I installed mysqlsh on the droplet and tried to connect to the mysql server. It failed when I tried to connect via private network, but it succeeded in connecting through the public network.

It appears that the issue is limited to private networking only.

Same here. Anyone find a solution?

Same issue - still searching for a solution - the public network works fine.

I’m having the same issue… solution is to use the public IP for now :/

Same issue here. The public host works but the private doesn’t.
