Can't execute SSL

[ALTFF]

I set "Yes" for both "Use Secure URLs on Storefront & Admin" in backend.

After saved, the site still in "information or insecurity" mode, and

the frontend not in normal displaying,

and get "ERR_TOO_MANY_REDIRECTS" message from admin page. 

Please help!

Just remove var/generation, var/page_cache and var/view_preprocessed folder from root.

Give full permission to var generation folder and pub/static folder.

Run below command,

php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy
php bin/magento cache:flush

Clear browser cache.

Update:

have you check your mod_rewrite is enable or not? If not enable please enable mod_rewrite.

if issue solved,Click Kudos/Accept as solutions.
