Comment (by bcolflesh):

 This still happens in 6.1.1 -

 2023/01/16 21:41:33 [error] 1166#1166: *222553 FastCGI sent in stderr:
 "PHP message: PHP Notice:  Undefined index: host in /my/path/wp-
 includes/canonical.php on line 689PHP message: PHP Notice:  Undefined
 index: host in /my/path/wp-includes/canonical.php on line 698PHP message:
 PHP Notice:  Undefined index: host in /my/path/wp-includes/canonical.php
 on line 701" while reading response header from upstream, client:
 99.99.100.99, server: 99.99.99.100, request: "GET / HTTP/1.0", upstream:
 "fastcgi://unix:/var/run/php/php7.4-fpm.sock:"

 Why not update the handler for cases when host is not set?
