Hi,

The error message in your log that is “unusual” is the following:

Caused by: java.net.SocketException: already connected

If you google it, there are some topics with solutions.

Maybe this is your case, have you set up Cloud SQL Proxy?

Thank you for the prompt response. I had not set up cloud SQL proxy as per the google documentation it was not required.

The real issue was that I had set up the sample instance with password ‘Cuba’ and was using postgres that resolved the issue.

I could see that the tables were being created well using the cloud shell but the application was not loading up.

Increased the number of instances in manual scaling to 2 but yielded no result.

I could see that the application was at-least trying to load up but running into some kind of problem loading up vaadin widget sets.

Added the following in the app.yaml file and it works well now.

Thank you for the support
