Hi! Attempting to renew an expired certificate on a Pi via certbot, and am getting the following error. Is there something I can do to renew?
--
My domain is: stream.no-soap.net
I ran this command: sudo certbot renew --dry-run
It produced this output:

Hi @maaaaaaaaaatt ,
I find that hint very often true.

Have you checked your DNS to ensure that your IP is current and correct?
How about any firewalls or port-forwarding?
4 Likes
Double checked my DNS, and confirmed it matched the output of sudo curl -4 ifconfig.co. Firewall and port forwarding look correct as well!
For port 80 for the HTTP Challenge?

Actually, realizing I have port 443 forwarding (this was the setup that worked well before the cert expired). Do I need to switch that to port 80, or add port 80 as well?
maaaaaaaaaatt:
add port 80 as well?
Yes you do; Port 80 needs to be accessible for the HTTP-01 Challenge.Hardenize Report: stream.no-soap.net

You need to add it. Both 80 and 443 need to be open.
Bruce5051:
Yes you do.

Okay, getting somewhere! Opened port 80 for forwarding, and am seeing the same debug result on my end.
When trying another sudo certbot renew --dry-run, I get the following:

Poking around further, and found that when I tried to take a look at the folder noted here:
All simulated renewals failed. The following certificates could not be renewed:
/etc/letsencrypt/live/stream.no-soap.net/fullchain.pem (failure)
That I got an access denied. Is that to be expected?

Would you show the entire error message like you had previously? There is lots we can derive from it.

Sure - there's not much of an error message beyond:

Okay then what was the command you typed?
Because I don't see how that could happen with this command

Sorry, I could have been more clear. The Permission denied message was when I tried to navigate to the /etc/letsencrypt folder.
when running sudo certbot renew --dry-run, I get the following error:

As for the cd command you may want to read this: User Guide — Certbot 2.12.0.dev0 documentation
The real problem though is the "502" in your renew ---dry-run. That is a gateway timeout and something going wrong in the nginx server block for port 80 (handling incoming HTTP requests).
Normally a port 80 block would not do much. You had some problems with ports earlier. Are you sending incoming port 80 to your nginx on port 80? And, still port 443 to nginx on port 443?
Otherwise, please show us the server block for port 80. Better would be to show entire output of this although info will be very long. An uppercase T is essential

So, HTTP requests for that domain name fall into that proxy statement and then fail with a 502. Happens for requests to your "home" page or for Let's Encrypt HTTP challenges
curl -i http://stream.no-soap.net
HTTP/1.1 502 Bad Gateway
Server: nginx/1.22.1
We don't need that proxy to work to make the challenge succeed. Although, you may want to debug why that fails. Presumably there is nothing listening on port 8080 but as I said it is not necessary for the LE challenge.
Instead, change that server block to look like this
server {
listen 80;
listen [::]:80;
server_name stream.no-soap.net;
location /.well-known/acme-challenge/ {
root (folder); # See below
}
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Port $server_port;
proxy_pass http://localhost:8080/;
}
}
The folder value must match the --webroot -w folder you used when creating this cert previously. You can find this in the this file./etc/letsencrypt/renewal/stream.no-soap.net.conf
As an example your default server block uses this folder:
maaaaaaaaaatt:
root /var/www/html;

Okay, updated the file to read:
# configuration file /etc/nginx/sites-enabled/stream.no-soap.net.conf:
server {
listen 80;
listen [::]:80;
server_name stream.no-soap.net;
location /.well-known/acme-challenge/ {
root /usr/share/icecast2/web/; # See below
}
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Forwarded-Port $server_port;
proxy_pass http://localhost:8080/;
}
}
Saved, and confirmed by running another sudo nginx -T.
Retried a dry run, and got the following:
