File does not exist - wp-index.php

Question

In PHP logs I keep getting errors like this:

does not exist: /home/user/domains/domain.net/public_html/wp-index.php, referer: http://domain.net/wp-index.php
File does not exist: /home/user/domains/domain.net/public_html/blog/wp-index.php, referer: http://domain.net/blog/wp-index.php

However, the referrers don't exist either, so I'm not sure where to track the problem down. What is causing the error? The blog itself seems to work fine. I'm just trying to eliminate the errors in the log.

WordPress 5.5.1

Not sure what to tag this question with.

[ed]

I could not find any instances of the string "wp-index.php" in my blog folder.

Here's a screenshot of the log. Is it an PHP error log or access log?

To investigate the issue, you can follow these steps:

1. Check site URL in settings - General, WordPress Address (URL) and Site Address (URL) If you have WordPress in a directory, make sure the installation process is right based on https://wordpress.org/support/article/giving-wordpress-its-own-directory/
2. Check .htaccess file to make sure there is no wrong rule. Check the documentation link on step 1.
3. Re-install WordPress from admin dashboard - Updates.
