issuing a certificate via yunohost's webinterface, or commandline (ssh) yunohost domain cert-renew www.mydomain.be gives this error Error: Domain www.mydomain.be does not seem to be accessible through HTTP. Please check the 'Web' category in the diagnosis for more info. (If you know what you are doing, use '--no-checks' to turn off those checks.) issue is i think the nginx redirection settings of custom webapp apps (http:// requests get forwarded to https:// ) eg. in /etc/nginx/conf.d/www.mydomain.be.d/wordpress.conf i commented following ‘rewrite’ https settings (you can use octothorp '#' character on the beginning of the line) #if ($scheme = http) { #rewrite ^ https://$server_name$request_uri? permanent; #} then restart nginx systemctl reload nginx and have a quick test (from another computer) curl http://www.mydomain.be 200 ok yunohost domain cert-renew www.mydomain.be --no-check ( or 'yunohost domain **cert-install** mydomain.be --no-checks' if there was a selfsigned cert and you want to get an letsencrypt issued one) after this, reset the changes in the nginx configuration & reload nginx... mais tuto bene a la fin toutlemonde content : test with curl (on laptop) ptr@eternit:~$ curl http://www.mydomain.be 301 Moved Permanently
