Hi @wallace11622,

It’s possible you haven’t configured properly your nginx configuration file. Can you please post back your conf and we’ll try to further provide you with info?

Kind regards,
Kalin

Hi @wallace11622,

Try commenting out the following bit

try_files $uri $uri/ =404;

and replace it with

location ~ /\.well-known/acme-challenge {
    root /path/to/web/root;
}

This should do the trick for you.

Kind regards,
Kalin
