Strange thing here.

If I try this with Free-form input:

Sqrt[(2^tLog[2])^2/(1 - 2^(2t))]

I have no problem...But if I try the same expresion in the Wolfram Alpha query input I get:

FetchURL::httperr: The request to URL http://api.wolframalpha.com/v1/query.jsp?appid=U2YPK6-9K5JY5YK6Y&input=x%3DSqrt%5B+%282%5Et+%2A+Log%5B2%5D%29+%5E2%2F+%281+-+2%5E%282+%2A+t%29+%29%5D&async=true&format=cell,minput,msound,dataformats\[Ellipsis] dows-x86-64&mclient=2&mmode=query&msessinfo=%7B%22Allowed%22+-%3E+%22Unknown%22%7D&languagecode=es&uuid=None&mlicense=1234-4321-123456&machineid=6202-78539-21191&sig=9ba3bda92b5d88b4f7ffdc0c4386b2e0 was not successful. The server returned the HTTP status code 403 ("Forbidden").

Someone know why?

Thanks
