Subdomain images require subdomain folder

I have two identical servers using DNS in a round robin. We found that one server is displaying images just fine, while the second server isn't displaying images. If I go to:

https://sub.domain.com/images/1.png

The image doesn't show up.

If I change the URL to:

https://sub.domain.com/sub/images/1.png

Then the image appears.

I have checked my htaccess and php configuration between the two servers, and can't find any differences. Can anyone shed some light on why this issue would occur?

 

I found that using a PHP call to display all variables, the document root is showing /home/user/public_html. I checked the subdomain files in /var/cpanel/userdata/{user}/{sub.domain.com}

The file contained the correct document root

subdomain point to wrong document root

This article shows the user appears to be having the same issue as me, but I didn't see a resolution. I have not tried deleting a subdomain and recreating since it appears from this thread that won't work.

Do you have ideas on how to troubleshoot this?

One of my servers is showing the document root correctly and the other is showing the document root as the /home/user/public_html and is missing the /subdomain at the end of the document root. Since the two servers are using identical WHM / Cpanel versions, the files and permissions are exactly the same, there must be a WHM / cPanel misconfiguration. I have several other wildcard domains with multiple subdomains, and none of them have issues on either server. The issue is narrowed down to a single domain with multiple subdomains all having the same issue.
