Mautic went down after cache clearing

You need to install SSL, I PMd you a tutorial, but there are many on the internet.
You need to use the one that fits your webserver, and operation system.

We opened nano be navigating to the right directory:
(I think it was)
cd /var/www/html/app/config

then we opened the config file:

nano local.php

Saving in nano is happening with:

CTRL + S
Y
-ENTER-

You got the error “too many redirects”.
The reason was, that your site URL was saved with “https” protocol in front. This is how Mautic calls itself.
When your visitors opened the page, your webserver directed the traffic to http, but Mautic claimed it is https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https, but your webserver didn’t agree, so redirected to http, but Mautic claimed it’s https…
