Fresh install LAMP from ports - FreeBSD 12.2 - Apache 24 - Mariadb 10.3 or 10.4 or 10.5 - PHP 7.3 or 7.4 (with required extensions) - Nextcloud 20.0.5 After initial setup the browser result in infinite loop redirect. No login page is shown. Similar to bug #236693 There are errors in nextcloud.log: "Could not detect any host in http:///data/htaccesstest.txt" Then any access of nextcloud result in infinite loop. In config/config.php there is missing the whole setup of array 'apps-path'. I added apps-path setup and the browser after login page result in showing "Internal error ..." Errors in nextcloud.log: "Doctrine\\DBAL\\EXCEPTION\\TableNotFoundException" The login page of nextcloud is not accessible anymore.
Finaly I made this workaround, after many attempts: Same installation of LAMP, but with PHP 7.2. It works without problem. Than it is possible to upgrade PHP to 7.4 and it also works. I didn´t found why it made loop redirects.
