I installed  0.9.9 on centos7, with nginix, mysql  no problems and then ran the letsencypt with iredmail procedure and I got the certificate error to go away and now I can't get to roundcube since it is pointing to the wrong place now.  What should the root be set to?

root         /opt/www/roundcubemail/index.php;

I get this error message

2019/03/14 23:10:26 [error] 1929#0: *30 "/opt/www/roundcubemail/index.php/index.html" is not found (20: Not a directory), client: 96.86.87.206, server: mail.livesentinel.io, request: "GET / HTTP/1.1", host: "mail.livesentinel.io"
