nginx proxy manager keeps being redirected to the default page

I installed HestiaCP, and then I added a domain and port to Nginx Proxy Manager (npm). Npm displays ‘Success! Your new web server is ready to use.’ However, when I enter the domain, and the domain has content, I can access it directly in my browser. Why does npm show ‘Success! Your new web server is ready to use.’? Is my npm blocked by the HestiaCP firewall?

Hello, you should use your ip with the port or your hostname with the port like this: or (or your selected port).

hello When I set the port to 8083, it displays a 504 Gateway Time-out… All settings in HestiaCP are default…

I’m using the default port 80 for the domain in HestiaCP…

I am sorry i understand wrong, you add new user and new domain and display this?

yes Where is the error occurring? When I use the http domain with port 80, it displays 'Success! Your new web server is ready to use

What kind of content does your domain have? Also why http and not https? didnt add an ssl? And did you try to clear your browser cache?

hestiacp has its own nginx proxy manager integrated, if u installed separately u need to fix it.
then after adding a domain u need to go /usr/local/hestia/data/templates/web/nginx/ and create templates with your port .
then edit domain and select the newly created template.
