Welcome to the Q&A Forum

I check and seems that your site is OK from mine side - GCE, Amazon EC2 and in Eastern Europe. There are few issues - SSL3, weak DH and files as: https://www.pouyasazan.org/IT-news/25876/css/css/css/css/css/css/css/css/css/css/css/css/css/tooltipster.css (breaking relative and absolute path), also no 404 page because everything return "200 OK" (soft 404). But they isn't critical for your site working and it works. Server works and i just hammering it with many requests. Please contact with Moz on mail here: help@moz.com or fill form there: https://moz.com/help/contact/pro to investigate your situation.
