My domain is: significado.xyz
My web server is (apache + nginx proxy):
The operating system my web server runs on is: CENTOS 7 64bits
I can login to a root shell on my machine: Yes
I’m using a control panel to manage my site : Vestacp
Months ago i’ve installed vesta then i’ve added some sites with LE all fine with this guide: https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-debian-9
2 days ago i buy some domains, and i try to add the domain with command letsencrypt-vesta admin significado.xyz there was an error saying the “The key authorization file from the server did not match”
after searching and even get limit install by the errors, some one says “remove your ipv6 from dns” (oi forgot to tell im using cloudflare, but still the trafffic its direct, with past domain worked just fine)
i check the dns from vesta and cloudflare and i dont see anything relatd to ipv6. even i try to disable ipv6 from vi /etc/sysconfig/network. didnt work either.
then i realized i have apache and nginx for proxy (i didnt cnofigure anything that option is on vestacp) then i just disabled that part and work it.
i just wanna ask how to solve this without disable nginx?
later i just wanna use nginx but that means i will lose https right?
thanks in advance, i mange a vps but theres many things i dont know
btw i tried to renew domains with: letsencrypt-vesta -a 90 admin domain and says: atd is not available. Is it installed? Renewals not scheduled.
