Issue Sporadic Site not Found message for newly installed WordPress pages

[darktime]

Hi, when we install a new WordPress site using WP Toolkit, we get sporadic site not found messages every 3 times it loads.

We suspect that this has been happening since the new WP Toolkit update (6.2.15-8047).

What have we tried?

- Installing multiple times
- Change from Apache FPM to Nginx
- Manual installation of WordPress

Log message:
Error 428 GET / HTTP/1.0

It only affects the new pages, all those installed 1-2 weeks ago do not have the problem.

Thank you!

This could be caused by the Plesk temporary domain as that requires a security dialog confirmation before the page is shown.

Thank you for your reply, I have confirmed the dialogue. What else could I do?

If I use a subdomain, the same thing happens.

Everyone who has not yet visited the website or doesn't accept cookies will see the dialog. If you use a subdomain to a real domain name it should not happen, but if you use a subdomain to a *.plesk.page domain, this will happen, too. It was a necessary tweak for the temporary domains, because too many people were abusing them for phishing.

Even with a normal domain, the problem occurs.

If it's not an issue with the *.plesk.page domain, the website itself might cause it or a DNS configuration that has additional A or AAAA records that do not point to the same website. This could lead to round-robin DNS where every n-th request is answered with a wrong IP address.

It seems that updating to 18.0.59 solved the problem for me.
