        for me ssl Let's Encrypt only works with apache! in about 5 vps whenever I install nginx the function of issuing ssl certificate Let's Encrypt stops working! and so some people can not enter my site, they say that the page is blank, and others can only access it with vpn. and it doesn't just happen with my server. and it does not matter the region BR OR USA the error is the same

          Hello, What does Let's Encrypt stop working show?
          Is the inaccessibility of some people restricting area access?
