I see two potential problems here:

- You have spaces in your ip address 192. 168. 1. 253  There should not 
be spaces after the periods. It should look like 192.168.1.253

- You are using port 3306. That is the database port. You need the http 
port, the default is 6544. leanfront does not access the database, 
everything goes through the backend.

Test the connection by running on a browser the ip address and port, 
like this : http://192.168.0.105:6544/

You should see a web display from the backend.
