Issue while renewing https certificate

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

I got an email stating that my certificate will expire in 20 days

My domain is: https://veratanlp.centralus.cloudapp.azure.com

I ran this command: sudo certbot renew

It produced this output:
All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/veratanlp.centralus.cloudapp.azure.com/fullchain.pem (failure)
http://veratanlp.centralus.cloudapp.azure.com/.well-known/acme-challenge/uxIJrkHyhoeFqsxA1vAcNz-dPq4-8JSo7NCqSShCBt8:
Timeout during connect (likely firewall problem)

To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you’re using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.

My web server is (include version): Apache/2.4.29 (Ubuntu)

The operating system my web server runs on is (include version): Ubuntu 18

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know):

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): certbot 0.28.0

Hi @an139530

your domain is invisible - https://check-your-website.server-daten.de/?q=veratanlp.centralus.cloudapp.azure.com

Only timeouts. You need a running webserver and an open port 80, so Letsencrypt is able to validate your domain name.

Hi
when you type https://veratanlp.centralus.cloudapp.azure.com](https://veratanlp.centralus.cloudapp.azure.com, aren’t you getting hello world!
?

No, there is a timeout. Use online tools to check that. Online tool -> timeout -> Letsencrypt can’t check your domain.

I asked the security team and according to them the domain is not visible outside.

Then you can’t use http validation to renew your certificate.

There are older certificates

How did you create these?

I created using Let’s encrypt Certbot.

Then share your renew configuration file.

Location:

/etc/letsencrypt/renewal

there is a file at that location veratanlp.centralus.cloudapp.azure.com.conf
are you talking about that?

What’s the content of that file?

Should I copy-paste here, or how?

sorry I did not get you earlier, this kind of data is there, please let me know if you have any questions

renew_before_expiry = 30 days

version = 0.28.0
archive_dir = /etc/letsencrypt/archive/veratanlp.centralus.cloudapp.azure.com
cert = /etc/letsencrypt/live/veratanlp.centralus.cloudapp.azure.com/cert.pem
privkey = /etc/letsencrypt/live/veratanlp.centralus.cloudapp.azure.com/privkey.pem
chain = /etc/letsencrypt/live/veratanlp.centralus.cloudapp.azure.com/chain.pem
fullchain = /etc/letsencrypt/live/veratanlp.centralus.cloudapp.azure.com/fullchain.pem

May I know what is supposed to be done in this?
