Can you try an up to date docker-stacks image, as suggested earlier? That will help narrow down the problem.
Hello there, @manics. I guess we’re not using a docker-stacks image here. My instance’s hub configuration is not being updated. That could be why default_url does not open during the launch. I compared the two configurations, and they are distinct. And I found this in the instance logs.

Do we need to update the singleuser image to 3.0.0?
Yes, you should upgrade singleuser image as well to have a consistent behavior. As you said, that might be your issue!
After upgrading the single user package on my sandbox image the config is now working.
Thank you for your support and time @mahendrapaipuri @manics.
