Server : Amazon with CDN Admin link : https://www.gleitsichtbrille.de/index.php/ag_supervista/
If I do the setting
'Use Secure URLs in Admin' => 'No', it is working fine and if I change to
'Yes' then it is showing an error of 'too many redirections please remove cache'.
I have already removed cache and session folder, still facing the same issue.
The site is live, so currently setting is
'Use Secure URLs in Admin' => 'No'.
