Add new domain to certificate

Hi all,

First of all sorry for rather long post!

Did have a look through the forums on this particular issue am having, which is how do i go about adding a new domain thats been added as an additional alias in the vhost config, the server is apache based.

Both domains ( & are publicly available with dns pointing to same box where their hosted on.
With separate landing pages working also over http/https but 301 redirects setup in vhost for each.

I have tried;

certbot --expand -d -d

sudo@Bot:/# certbot --expand -d -d

You have an existing certificate that contains a portion of the domains you
requested (ref: /etc/letsencrypt/renewal/

It contains these names:

Hi @aleon

the tls-sni-01 - challenge is deprecated, support ends 2019-02-13. You can't use it with a new domain, so it's impossible that such a command works.

is better, but to check your configuration: What's your domain names?

I also recommend feeding your domain into as it can be really useful to diagnose problems.

Hi guys,

Thanks for your input, much appreciated.

I have pm’ed you Juergen on the site sin questions.

Will try letsdebug, interesting site thanks.

All OK!

Well here I am asking :slight_smile:

Sorry, we’ll need your real domain name to help. Usually domains are not really confidential as all anyone can really do is visit the website.

Thanks, got your DM. If you look at the verbose output of you’ll see your previous failed authorization as a 403 unauthorized, and if I try it manually I get an error 500 ‘Sorry, our script crashed. Oh dear’

I think your content management system/app is not allowing requests through to the /.well-known/acme-challenge path. You can test this by putting your own (extensionless) text file at that path in your website, then see if you can browse to that file. Once you can browse to a file you create at that path, your challenges will probably also start working.

FWIW this is not an indication of a problem, which is why I hid it under "verbose".

But the rest of your post seems like good advice - OP should check the webroot.

Thanks for prompt response :slight_smile:
Am not sure if i am following you on the 2nd part of your suggestion but i get: “Sorry, our script crashed. Oh dear”

When browsing the domainname1/test1 but on domainname2/test1 get the proverbial site not secure warnings!

the content of test1 is just some words…

So 500 error i am getting is the issue here?

OK i think i solved the error 500 on the file now.

had this on my .htaccess file

Header set Access-Control-Allow-Origin: https://olddomain https://newdomain

So just commented this out for now, as I added newdomain to this line while trying to add domain as my original post.

That worked!!!

Thanks. Looks like the problem is now solved.

There is a new LE certificate created today :wink:

Thanks for your advise :slight_smile:

Now todo same on Nginx now… its Friday I think i give it a rest and not break anything.

Hi all,

Just revisiting this as not sure autor-renewal of certficate will work now.

So I expanded the certificate for existing certificate to include a new name int he SAN (subject alternative names) using:

certbot --webroot -w /path/to/ certonly -d -d

Does that mean the auto-renewal for this sites set in apache2 will not auto renewal?
