Cloud SQL Connection issue when running gcloud app deploy

[Ferry Ariawan]

Hi,

I use Google App Engine (nodeJs) and Google Cloud SQL (Mysql 5.7). Yesterday (about 24 hours ago) I did a gcloud deploy and it deployed perfectly, and when i did gcloud deploy this afternoon the app keep failing to start.

It keeps giving this error message

2020/01/10 13:08:54 Reading data from local connection on /cloudsql/my-app-name:asia-south1:my-instance-name had error: read unix /cloudsql/my-app-name:asia-south1:my-instance-name->@: read: connection reset by peer

Hi Ferry,

This could be due to the connections to the Cloud SQL that were previously established. However, if you still experience the issue, I would suggest to create a Private Issue Tracker and provide instance name along with the project number for further investigation.
