Original GitHub issue: https://github.com/0xJacky/nginx-ui/issues/368

Describe the bug
I just installed nginx-ui with docker.
I want to create my first reverse proxy for nginx-ui (nui.domain.tld -> IP:80) but I can't get a valid ssl Let's Encrypt certificate.
domain.tld is my domain where I set DNS A records (domain + *.domain) pointing to my external VPS IP address.

To Reproduce
Steps to reproduce the behavior:

Manages Sites > Add Site:
Configuration name: basic
Listen: 80
server_name: nui.domain.tld
Next
Enable TLS ✅
Do you want to enable TLS popup: OK
Encrypt website with Let's Encrypt ✅
Challenge method: HTT01
Key Tape: RSA2048
ACME user: System Initial User (already setup my Let's Encrypt account)
Next

The popup opens and nothing happen after Getting the certificate, please wait...

Expected behavior
The TLS certificate is generated from Let's Encrypt and set to server nui.domain.tld.
