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=ottawakaraoke.com](https://crt.sh/?q=ottawakaraoke.com)), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help. My domain is: [ottawakaraoke.com](http://ottawakaraoke.com) I ran this command: sudo certbot --apache It produced this output: Which names would you like to activate HTTPS for? * * * 1: [canadakaraoke.com](http://canadakaraoke.com) 2: [www.canadakaraoke.com](http://www.canadakaraoke.com) 3: [karaokeottawa.com](http://karaokeottawa.com) 4: karaokeottawa.ca 5: www.karaokeottawa.ca 6: [www.karaokeottawa.com](http://www.karaokeottawa.com) 7: [ottawakaraoke.com](http://ottawakaraoke.com) 8: ottawakaraoke.ca 9: [sing.ottawakaraoke.com](http://sing.ottawakaraoke.com) 10: www.ottawakaraoke.ca 11: [www.ottawakaraoke.com](http://www.ottawakaraoke.com) My web server is (include version): apache The operating system my web server runs on is (include version): debian 8 jessie My hosting provider, if applicable, is: ovh I can login to a root shell on my machine (yes or no, or I don’t know): yes I’m using a control panel to manage my site (no, or provide the name and version of the control panel): putty The version of my client is (e.g. output of `certbot --version` or `certbot-auto --version` if you’re using Certbot): latest version of certbot I changed my ip address and am using a new host i receive the following error 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. I have a new ip address, how what is the next step? ---

I have already posted the error message. I’m using that command to renew the certificate. ---

> [@ianarman1](#): > > The server could not connect to the client to verify the domain : OK, this is the problem--the Let's Encrypt servers can't connect to your server at all. Is your new IP address 51.79.54.130? Because that's what a DNS query is returning: ```plaintext dan@Dan-MacBook-Pro-2453  ~  host canadakaraoke.com canadakaraoke.com has address 51.79.54.130 dan@Dan-MacBook-Pro-2453  ~  host karaokeottawa.com karaokeottawa.com has address 51.79.54.130 dan@Dan-MacBook-Pro-2453  ~  host ottawakaraoke.ca ottawakaraoke.ca has address 51.79.54.130 dan@Dan-MacBook-Pro-2453  ~  host ottawakaraoke.com ottawakaraoke.com has address 51.79.54.130 ``` If it isn't, as I suggested earlier, update your DNS records. If that's correct, make sure Apache is running on port 80 and that you don't have a firewall blocking anything on that port. ---
