Why do static files keep downloading over HTTP after enabling HTTPS?

Question

Magento

I set Secure Base URL to https://magento22.local , did setup:upgrade

But links to static files are still displayed from http:// , and the browser blocks files as mixed content:

I tried to clear all caches, incl. manually, all files included in production mode - the same.
What's the matter? Why doesn't magenta use HTTPS for addresses?
Enabling "Use Secure URLs on Storefront" didn't change anything.

Answer 1

The whole problem turned out to be an underconfigured local SSL. I didn't add this to the site's conf file:

<VirtualHost *:443>

   ...

SSLEngine on

SSLCertificateFile /etc/ssl/certs/apache-selfsigned.crt
SSLCertificateKeyFile /etc/ssl/private/apache-selfsigned.key

<FilesMatch "\.(cgi|shtml|phtml|php)$">
SSLOptions +StdEnvVars
</FilesMatch>
<Directory /usr/lib/cgi-bin>
SSLOptions +StdEnvVars
</Directory>
</VirtualHost>

As a result, Magenta's isSecure() method returned false (I thought that Magenta only checks what protocol the address is requested for, but it checks the values ​​in $_SERVER - HTTPS and PORT) and the settings from the unsecure section were used.

Answer 2

Put https everywhere
