Thank you for your help

As this seems to be a setup issue I would like to ask you to raise your question in the forums: https://help.nextcloud.com

Usually you see a behavior like this if the session directory is not writable by php.

There's also #13431 :(

I use Redis for PHP session. I have the same problem, but I suspect that this is a compatibility issue between PHP 7.3.6 and Redis(5.0.5).
In the case of PHP 7.3, throw an error in the following PHP session_start() line. If this is PHP7.1 or 7.2, no error occurs and login does not loop. *It might have happened, but it worked with PHP7.3.3 and PHP7.3.5 without problems.
Of course, this problem doesn't occur if I don't use Redis for PHP session.

<?php
session_start();
echo "save_handler=" . ini_get("session.save_handler") . "\n";
echo "save_path=" . ini_get("session.save_path") . "\n";
echo "session_id=" . session_id() . "\n";
$_SESSION['libname'] = "PhpRedis";
?>
