Can't login after fresh install

First of all, I note that I'm installing the owncloud not for the first time. And always all went good till now.
Once installed, I can not login into my server.
Apache logfile and owncloud logfile are absolutely clear.
And these empty logs bother me the most!

What am I doing:

mysql -uroot -p
GRANT ALL ON cloud.* to 'cloud'@'localhost' IDENTIFIED BY 'db_pass';

Then I enter on https://mysite, fill in the appropriate fields and see login prompt.
And when I try to log in the start page is reload and doing nothing!

Just address changed to .../index.php/login?redirect_url=%252Findex.php%252Fapps%252Ffiles%252F

Please, help me to fix this. I'm suffering the third day :frowning:

I has tried in version 10.0.1 & 10.0.2 and even nextcloud 12.0.0 - same result.
What data do I need to provide to better understand the problem?

Have you tried it without the redirect and http?

Yes. Just tried to disable the rewrite module in site.conf. Log in via http. The result is the same.

I’ve got the same issue, described here. Had you been able to solve this?
