Magento – Magento2 CSS was blocked due to MIME type mismatch (X-Content-Type-Options: nosniff)

cssmagento2

I am using Magento 2 in Windows 10 using xampp.

I have installed magento2 and it was running perfectly. After that, I migrate data from magento1 with migration tool.

Now I am having an error with the resource from “
(CSS path)” was blocked due to MIME type mismatch (X-Content-Type-Options: nosniff).

Already tried to deploy static content many times with cache and index refresh. URL rewrite is already ON.

Can anyone please help me out?

Thanks

Download the .htaccess file for your specific magento version and put it inside the pub/static folder in the default magento directory and these errors should vanish.

I also faced a very similar issue. After a lot of deliberation I was able to understand that this problem mainly occurred because I deleted the .htaccess file inside the pub/static folder.

Remove all files from var/ folder.
Check for .htaccess in pub/static. If not exists, take a file from a fresh setup.

Run the following commands

php bin/magento setup:static-content:deploy -f
php bin/magento indexer:reindex
php bin/magento cache:clean
