I am running 2nd generation instance.
I am able to connect locally but when I run gcloud app deploy
I keep getting the error Error establishing a database connection
I have tried using root
and a blank password and still does not work.
I have followed instructions from https://cloud.google.com/php/tutorials/wordpress-app-engine-flexible and still getting the error.
See my wp-config.php page as well as the screenshot from cloud.google.com everything matches but still getting the error.
I have followed the [tutorial](https://cloud.google.com/php/tutorials/wordpress-app-engine-flexible ) you mentioned and got the same issue. When I followed instructions on GitHub of the sample it works as expected.
An important difference I found is that the official tutorial doesn't mention cron.yaml:
gcloud app deploy
and in the repo:
gcloud app deploy \
--promote --stop-previous-version app.yaml cron.yaml
I would follow the github version only.
