HTTP_UPDATE_FAILD Error (-104): Wrong HTTP Code

Hi All
I am using ESP8266 to test httpUpdate. Tried both of these update methods

```
//t_httpUpdate_return ret = ESPhttpUpdate.update(client, "http://rohini.ultimatefreehost.in/httpUpdate.bin"); -->Did not work

t_httpUpdate_return ret = ESPhttpUpdate.update(client, "http://rohini.ultimatefreehost.in", 80, "httpUpdate.bin"); ->> getting HTTP_UPDATE_FAILD Error (-104): Wrong HTTP Code
```
Debug messages
