Original GitHub issue: https://github.com/0xJacky/nginx-ui/issues/110

I just installed nginx-ui on ubuntu server with the linux installscript but when i start the service with sudo systemctl start nginx-ui it gives me this output in the systemctl status:

nginx-ui.service - Yet another WebUI for Nginx
     Loaded: loaded (/etc/systemd/system/nginx-ui.service; enabled; vendor preset: enabled)

It looks like AutoCert is having memory issues.
Would it be possible to run nginx-ui without ssl?

To Reproduce
Steps to reproduce the behavior:

Install nginx-ui with the linux installscript
Run the service with sudo systemctl start nginx-ui
Run sudo systemctl status nginx-ui
See error

Expected behavior
I was expecting to see the install screen when visiting <server_ip>:9000/install but i got a timeout instead

Info

Server OS: Ubuntu 22.04.2
Server Arch: LTS x86_64
Nginx UI Version: 1.8.3
Browser: Arc, Safari

Looks like nginx-ui requires you to run it with ssl through nginx.
I added the nginx-ui to my nginx configuration with an ssl certificate and now it works.

If you’re using a cloud server, please make sure that port 9000 is open.

Yeah port 9000 wasn't forwarded so I had to run it through Nginx on port 443
