My domain is: forum.aoecoin.io www.aoecoin.io …etc
I ran this command: sudo certbot --authenticator standalone --installer nginx -d forum.aoecoin.io --pre-hook “service nginx stop” --post-hook “service nginx start”
It produced this output: Failed authorization procedure. www.aoecoin.io (tls-sni-01): urn:acme:error:tls :: The server experienced a TLS error during domain verification :: remote error: tls: handshake failure
My web server is (include version): Nginx
The operating system my web server runs on is (include version): Ubuntu 16.04
My hosting provider, if applicable, is: Digitalocean, Cloudflare
I can login to a root shell on my machine (yes or no, or I don’t know): Yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): No
I’ve research that it’s has something to do with Clouddflare and I need to use the http-01 challenge instead. How can I do that? I’m a web developer and there’s no server admin here. I just get my way around and get everything working but now the certificate expire and I can’t renew it. The command above used to work fine last time I renew my certificate but not this time.
