Folder ".well-known/acme-challenge" disappeared

Help
#1

I’m relatively ignorant about how Certbot works. However, I have had a server with a Certbot cert for a year or so. Cron job set up to renew, and normally it renews 30 days before expiry with no problem. The cron job ran early this morning and got a 404 on /.well-known/acme-challenge! I’ve looked around my file system and cannot find a .well-known folder. I don’t see an Alias in the Apache config files.

I did revoke a test certificate a month or so ago, and it is possible that I touched something at that time that messed things up… Too long ago to remember what else I did at the same time.

I’ve looked at other queries on community pages, but nothing seems similar enough. Should I see a .well-known folder? Any ideas where it would be? If it isn’t there, is there some way to recreate it? The website would need to continue functioning throughout.
Thanks!

My domain is: bslbeam.co.uk

I ran this command:
sudo certbot renew

It produced this output:

Hi @Sherratt

if you use the Apache authenticator, Letsencrypt shouldn’t see a redirect to https.

Looks like your configuration is buggy.

What says

apachectl -S

Remove all duplicated definitions, every combination of port and domain name must be unique.

Thanks Juergen. It definitely looks like it is buggy - see below! I’ll dig into the conf file

AH00526: Syntax error on line 367 of /etc/apache2/sites-enabled/bslbeam-secure.conf:
SSLCertificateFile: file ‘/etc/letsencrypt/live/bslbeam.co.uk/fullchain.pem’ does not exist or is empty
Action ‘-S’ failed.
The Apache error log may have more information.

Looked at config files and there are only 2 virtual hosts defined, one on port 80 and the other on 443.

However, the *:80 virtual host rewrites to https - wouldn’t that redirect Letsencrypt to https? In any case, it has been like that for years, and hasn’t blocked the cert renewal since I changed over to Letsencrypt

The cert file that apachectl says does not exist, is where it is supposed to be and isn’t empty! I checked the symlink is pointing to the most recent cert file, and
cat /etc/letsencrypt/live/bslbeam.co.uk/fullchain.pem
looks like a normal cert.

I wondered whether there might be a syntax error in the conf file prior to line 367, but I can’t see any problems.

What about the “.well-known” directory? Should it exist?

Run it as root or sudo.

As written: If you use --apache, another definition is included, so that should be skipped. But that doesn’t work, may be that vHost isn’t used or your configuration is too complex. Perhaps use the webroot of the https version with --webroot.

You should upgrade this machine.

are port 80 and 443 sharing a DocumentRoot? I suspect your redirect is too aggressive and breaks http-01 verification. Can you show us the files in /etc/apache2/sites-enabled/?

Yep, its in plan. Although I had thought it was 16.04.6 !

Does anyone know whether there should be a “.well-known” folder?

#10

Usually, there shouldn’t. Certbot will create it if there isn’t one.

But be aware that there could be a .well-known and other stuff, unrelated to acme-challenge, could be in there.

Certbot will create it if there isn’t one.

Thanks. I assume it would have been created at the time Certbot was first run. Given that it wasn’t getting 404s before, and now it is, I guess .well-known has somehow been deleted!

If certbot creates it, it will remove it after. But that depends on your authenticator plugin: are you using --apache or --webroot?

Plugins selected: Authenticator apache, Installer None

From memory, when it was first set up, there were some glitches when trying with --apache, so may have ended up using --webroot. However, whichever was used, the Cron job renewal has gone through every time until now, so I’m surprised it is now getting a 404.

Maybe better to manually try cert-only?

No, just show us what your apache configuration looks like.

By the way, you might already be aware of this, but --webroot uses a /.well-known/acme-challenge in your existing webroot, while --apache doesn’t (it makes its own path and modifies your Apache configuration to point at it, then modifies your Apache configuration back after the authentication process is complete).

Sorry about the delay. Other things have got in the way. Still looking for a solution to this!

Thanks schoen. I wasn’t aware of that. In which case the answer to a previous question should have been I am using --webroot.

The config file gets updated fairly frequently and is probably more complicated than it needs to be! Overnight I put up a much simplified config file taking out the layers of redirects that are usually there. The renew command still came back saying it had hit a 404.

There are 2 active config files. Any ideas?

    #   The safe and default but still SSL/TLS standard compliant shutdown

    #   the close notify alert from client. When you need a different shutdown
    #   approach you can use one of the following variables:
    #   o ssl-unclean-shutdown:
    #     This forces an unclean shutdown when the connection is closed, i.e. no
    #     SSL close notify alert is send or allowed to received.  This violates
    #     the SSL/TLS standard but is needed for some brain-dead browsers. Use
    #     this when you receive I/O errors because of the standard approach where
    #     mod_ssl sends the close notify alert.
    #   o ssl-accurate-shutdown:
    #     This forces an accurate shutdown when the connection is closed, i.e. a
    #     SSL close notify alert is send and mod_ssl waits for the close notify
    #     alert of the client. This is 100% SSL/TLS standard compliant, but in
    #     practice often causes hanging connections with brain-dead browsers. Use
    #     this only for browsers where you know that their SSL implementation
    #     works correctly.
    #   Notice: Most problems of broken clients are also related to the HTTP
    #   keep-alive facility, so you usually additionally want to disable
    #   keep-alive for those clients, too. Use variable "nokeepalive" for this.
    #   Similarly, one has to force some clients to use HTTP/1.0 to workaround
    #   their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
    #   "force-response-1.0" for this.

That’s still a lot of rewrite rules and aliases… some might interfere with the authenticator.

Your website works, right?

Yes, it works. The certificate is still valid for a few more days. The certbot command you suggested still gives an error:
