How to setup ssh key login for a different user?

Question

I am able to setup ssh key login for root user to my remote system from my local machine. Now I have created another user in my remote system like this,

sudo useradd --system --gid webapps --shell /bin/bash --home /webapps/hello_django hello

So, the name of the new user is hello. Home directory for this user is /webapps/hello_django.

Now I made hello as the owner of the directory, like this sudo chown hello /webapps/hello_django/

I certainly have created a password for the user as well.

Now in my local system I have created another pair of public and private key using ssh-keygen. And added the public key to /webapps/hello_django/.ssh/authorized_keys file in my remote machine. I am still not able to login to my machine using this user hello. For my root user, I followed the same process and it's working perfectly. What am I missing?

First thing is checking error log on server, which is usually more verbose then the one from client. It will probably tell you that you have wrong permissions on some way to the authorized_keys. After fixing accordingly, it should start to work for you as expected.
