port on live server

I have just successfully started my first wordpress blog. I have it all installed correctly on my localhost, but now I’ve transferred it to the live server. I’ve changed the database connections in the wp-config. But when I try to access the blog I get an error
The connection was refused when attempting to contact https://www.jbaykids.co.za:81. Where is it getting :81 from ? Does this need to be configured somewhere for the live server ? My apache server on localhost uses 81.

Please help. I am new to both wordpress & php.

Thanks
