Internal Server Error after configuration to 443 port

I try to enter in my site, but it writes this error.
error-nc
It began to appear after the configuration of the site on port 443. I checked /var/log/httpd/error_log and saw this:

XXX.XXX.XXX.XXX - - [06/Feb/2019:16:03:26 +0200] "GET / HTTP/1.1" 500 4587
XXX.XXX.XXX.XXX - - [06/Feb/2019:16:03:26 +0200] "GET /js/core/merged-template-prepend.js?v=deaa0a23-6 HTTP/1.1" 500 4767

What is it? How to fix it?

As a first try you could do a
occ maintenance:repair

Then you could enable debugging in the config.php
‘debug’ => true,
and check the nextcloud -logfile

  1. I did occ maintenance:repair. Nothing.
  2. Enable debug mode. See that:
    error-nc-2
    error-nc-2726×523 153 KB
  3. nextcloud logfile write code 200:
    ::1 - - [06/Feb/2019:17:17:18 +0200] "OPTIONS * HTTP/1.0" 200 - "-" "Apache/2.4.37 (Unix) OpenSSL/1.1.1a PHP/7.3.1 (internal dummy connection)"
