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.
My domain is: otrs.czics.ru
I ran this command: sudo certbot-auto renew
It produced this output:

Connection reset by peerTo 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):
Server version: Apache/2.4.7 (Ubuntu)
Server built: Oct 14 2015 14:20:21
The operating system my web server runs on is (include version):
3.13.0-76-generic #120-Ubuntu SMP Mon Jan 18 15:59:10 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know): only sudo
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 0.31.0
The server suddenly stopped updating certificates automatically; it can be accessed from the Internet on port 443. So i try to renew manualy, but has this error. Please, help.
