after upgrade to joomla 4.3.4 got error - This page isn’t working. ERR_TOO_MANY_REDIRECTS

[Skyluck]

I upgraded my website from joomla 3.10.12 to 4.3.4

The site with joomla 3.10.12 was made FORCE HTTP - Entire site (in global configurations) and has free SSL on hosting account and the site was shown on google chrome as secure (as it is needed)

After upgrade to joomla 4.3.4  I got  "This page isn’t working. ERR_TOO_MANY_REDIRECTS"
I changed  Force HTTPS - > "Administrator only" and the site front-end appear , but shown as "NOT SECURE" (the administrator link loads as Secure). PHP 8.0
All cache - browser , backend is cleared.

Would appreciate for help - how to make site SECURE again on joomla 4.3.4

According viewtopic.php?t=995386 --->
configuration.php
public $live_site = '';
public $force_ssl = 2;

on my website it is so.

You may have something on your site that is using an insecure url. Look at the page source and see if there are any instances of http:// - you should expect to find some in your http version if you are operating a multi-lingual site. You could provide a site link for others to look at.

Hi, ceford!
Thanks a lot for supporting replay.

As I am not so deep in programming , to understand the page source code is tough for me.
However somehow your messega gave me impulse and I checked all plugins on upgraded website. Compared with plugin list on old site version with joomla 3.10.12 (enabe/disable) and found few differences, changed that and Vuala the site is SECURE .. and I feel so much relief.
