The immediate thing that strikes me is that "127.0.0.1" should be {127,0,0,1}. In gen_tcp (erlang in general) the address is a tuple not a string.
See man 3 inet for more info.
Debugging becomes easier with experience. function_clause means you tried to call a function with the wrong argument type. Probably because you tried to pass a list (aka string) instead of a tuple to connect().
The rest of that section after function_clause is a stack trace. In this case it doesn't tell you much but it would be helpful if the failure occurred deeper into a call stack.

client([Port]) ->
case gen_tcp:connect("127.0.0.1", Port, [list,{packet,0}]) of
{ok, Socket} ->
gen_tcp:send(Socket,"auth iltd!dy69?\r\n\r\n"),
gen_tcp:send(Socket,"event plain text\r\n\r\n"),
loop(Socket);
{error, Reason} ->
print_stuff([Reason]),
ok
end.
