May be your proxies are invalid or a custom error.

- Not all proxies pass along detectable information.

You need addon, which runs multi-threaded connections and can retrieve the `Dead` or `Alive` status for bulk check, a list of domains or URL’s per minute.

Or

The simplest was is to simply catch the IOError exception from urllib:

```auto
try:
    urllib.urlopen(
        "http://example.com",
        proxies={'http':'http://example.com:8080'}
    )
except IOError:
    print "Connection error! (Check proxy)"
else:
    print "All was fine"

```

**for python 3, check below link**
