Hello Let's Encrypt community.
I have a problem when I want to generate my certificate, I hope someone can help me, I don't know much about this domain.
First Step on my PC I launch this command:
certbot certonly -d collecte-staging.westeurope.cloudapp.azure.com --manual
I get this result :
Saving debug log to C:\Certbot\log\letsencrypt.log
Requesting a certificate for collecte-staging.westeurope.cloudapp.azure.com
Create a file containing just this data:
And make it available on your web server at this URL:
Press Enter to Continue
Then I connect with ssh on server collecte-staging.westeurope.cloudapp.azure.com- and I execute this :
sudo node acme-challenge.webpack.js fyFm7w4czIlZ2BQQy-rbr5TiTTt8b8HMCHZ1J4n9jtk fyFm7w4czIlZ2BQQy-rbr5TiTTt8b8HMCHZ1J4n9jtk.-oKv-0KJrKJLICHU83EVyNJIVmAbJ9oRm6omRGoDnJ8
I get this result :

And finally I click on enter on my PC again and I get this error :
Certbot failed to authenticate some domains (authenticator: manual). The Certificate Authority reported these problems:
Detail: 188.8.131.52: Fetching http://collecte-staging.westeurope.cloudapp.azure.com/.well-known/acme-challenge/fyFm7w4czIlZ2BQQy-rbr5TiTTt8b8HMCHZ1J4n9jtk: Timeout during connect (likely firewall problem)
Hint: The Certificate Authority failed to verify the manually created challenge files. Ensure that you created these in the correct location.
Some challenges have failed.
Ask for help or search for solutions at https://community.letsencrypt.org. See the logfile C:\Certbot\log\letsencrypt.log or re-run Certbot with -v for more details.
I try to see in iptables if firewall had problem but they seem good, since I have a second server with almost the same settings and I don't have the same problem on it and I already generate a certificate on this one to 3 month ago.
I can provide the result of iptables if that can help to find the fix, the only thing I know is that one of my colleague made some manipulation this morning and maybe disconnect some services but I don't know which one.
My web server is (include version): Apache 2.4.29.
The operating system my web server runs on is (include version): Ubuntu
Thank you and my apology for my english,
