Don't use the \\.  That's a windows networking convention, and it does
not apply if you are using http.  Your error messages tell you this. 
The first one (r'http://\\pc_name:8000') could not resolve the address. 
The second one reached the server just fine, but the server rejected the
client's request.  So now the issue is why is the request being
rejected?  Did you check your firewall to see if it is blocking access
to port 8000 on the ethernet adapter?
