My domain is: dezorgagenda.nl
I ran this command: certbot certonly --dry-run --manual
It produced this output: Failed authorization procedure. www.dezorgagenda.nl (http-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching http://www.dezorgagenda.nl/.well-known/acme-challenge/ifM-TTublDVlYz73VBcj3XIPUqzCySqRWQXX0gtY43M: Timeout
My web server is (include version): nginx/1.10.2
The operating system my web server runs on is (include version): Ubuntu 16.04
My hosting provider, if applicable, is: self
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, terminal
I tried : certbot certonly --dry-run --standalone --preferred-challenges http-01 --http-01-port 80 and
certbot certonly --dry-run --webroot --webroot-path=_PATH -d www.dezorgagenda.nl
and same reply. Failed authorization procedure.......
I removed the HSTS from nginx and is now running bare port 80 setting, still no fix.
In the browser i can receive and download the acme file, when i use the manual option, but still LE doesnt connect to the server. Any ideas?
