I'm trying to get a website through Scrapy in the shell,
$ scrapy shell -s NAME="Mozilla/5.0" "http://www.yapo.cl/chile/inmuebles?ca=15_s&l=0&cmn=&st=a"
2017-08-21 20:55:07 [scrapy.downloadermiddlewares.retry] DEBUG: Gave up retrying <GET http://www.yapo.cl/chile/inmuebles?ca=15_s&l=0&cmn=&st=a> (failed 3 times): 504 Gateway Time-out
but Scrapy through me a 504 error which I cannot figure out, any guess what could it be?.
