I am running magento 2.1.5 and every thing was working fine. Suddenly my CSS and Js files are not loading I am getting error

 http://mymagentourl.com/pub/static/version1491202457/frontend/Magento/luma/en_US/css/styles-m.css” was blocked due to MIME type mismatch (X-Content-Type-Options: nosniff).

what is the meaning of was blocked due to MIME type mismatch (X-Content-Type-Options: nosniff).

I am running magento in nginx Web Server and my mode is production. I tried

  • remove Var/* folder
  • re deploy static content
  • remove cache
  • flush cache

I am not able to understand why my css and js is not loading?

  • It looks like the same problem: magento.stackexchange.com/questions/152625/… – Nikola Apr 3 '17 at 7:14
  • Possible but there is no accepted solution moreover I tried those too. @Nikola – Priyank Apr 3 '17 at 7:16
  • there is something wrong in nginx rewrite. – MagenX Apr 4 '17 at 16:43
  • it was working well before and there has been no changes after then. – Priyank Apr 5 '17 at 4:44

Navigate to your database and perform following steps:-

  • Find core_config_data table and open it.
  • Add a new row and provide "dev/static/sign" under path and "0" under value (without quotes) and leave other fields unchanged and save it.
  • flush cache php bin/magento cache:flush
  • perform static content deploy php bin/magento setup:static-content:deploy
  • Ya had that solution in mind and done that but this removes the dynamic generation of static file url of version which is removed. So is this ok? – Priyank Apr 3 '17 at 8:34
  • Please let me know about your server environment (linux or windows) and if the problem is browser depended or not. – Vivek Kumar Apr 3 '17 at 9:22
  • Linux with nginx web server no its not browser dependent. – Priyank Apr 4 '17 at 4:52
