Fresh install RoundCube not working

[kko]

After trying to open https://webmail.domain.tld i got this:

/var/log/roundcube have only one file session.log

/var/log/nginx/domains/webmail.domain.tld.error.log have only this warnings:
[error] 2087502#2087502: *806076 FastCGI sent in stderr: “PHP message: PHP Warning: Undefined array key “temp_dir” in /var/lib/roundcube/program/lib/Roundcube/rcube_config.php on line 233; PHP message: PHP Warning: Undefined array key “temp_dir” in /var/lib/roundcube/program/lib/Roundcube/rcube_config.php on line 233; PHP message: PHP Warning: Undefined array key “drafts_mbox” in /var/lib/roundcube/program/lib/Roundcube/rcube_config.php on line 243; PHP message: PHP Warning: Undefined array key “junk_mbox” in /var/lib/roundcube/program/lib/Roundcube/rcube_config.php on line 243; PHP message: PHP Warning: Undefined array key “sent_mbox” in /var/lib/roundcube/program/lib/Roundcube/rcube_config.php on line 243; PHP message: PHP Warning: Undefined array key “trash_mbox” in /var/lib/roundcube/program/lib/Roundcube/rcube_config.php on line 243; PHP message: PHP Warning: Undefined array key “log_driver” in /var/lib/roundcube/program/lib/Roundcube/rcube_config.php on line 247” while reading response header from upstream, client: xxx.xxx.xxx.xxx, server: webmail.domain.tld, request: “GET / HTTP/2.0”, upstream: “fastcgi://127.0.0.1:9000”, host: “webmail.domain.tld”

I used nginx + php8.3-fpm
exim and dovecot works nice!
How i can fix that?
