Just tested on my end, and I won't confirm the issue.
Make sure you've got no outdated templates in /usr/local/directadmin/data/templates/custom/ and /usr/local/directadmin/data/templates/
If you have make sure that you see there:
Code:
listen |IP|:|PORT_80|;
in nginx templates.
And make sure your Directadmin version is the current:
Code:
# /usr/local/directadmin/directadmin v
Version: DirectAdmin v.1.49.1
