In fact, trying to configure the client last.fm using 3proxy.
But I can't.
customer last.fm displays a connection error.

Through the browser all connections are working fine. In client last.FM tried socks and http port error just only for http, socks if nothing just not working.

config 3proxy:
/usr/local/3proxy# cat 3proxy.cfg
#!/usr/local/bin/3proxy
# Yes, 3proxy.cfg can be executable, in this case you should place
# something like
#config /usr/local/3proxy/3proxy.cfg
# to show which configuration 3proxy should re-read on realod.
# We can configure nservers to avoid unsafe gethostbyname() usage
