Hi @all,
I was following this tutorial to install SSL on my droplet. How To Secure Apache with Let’s Encrypt on Ubuntu 16.04
But for some reason I am getting this error: Failed authorization procedure. topladylingerie.co.ke (tls-sni-01): urn:acme:err or:connection :: The server could not connect to the client to verify the domain :: Connection refused, www.topladylingerie.co.ke (tls-sni-01): urn:acme:error:c onnection :: The server could not connect to the client to verify the domain :: Connection refused IMPORTANT NOTES: The following errors were reported by the server: Domain: topladylingerie.co.ke Type: connection Detail: Connection refused
Domain: www.topladylingerie.co.ke Type: connection Detail: Connection refused
To fix these errors, please make sure that your domain name was entered correctly and the DNS A 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.
And I have checked the firewall status, here is the ufw status: Status: active To Action From Apache Full ALLOW Anywhere OpenSSH ALLOW Anywhere 80 ALLOW Anywhere 443 ALLOW Anywhere Apache Full (v6) ALLOW Anywhere (v6) OpenSSH (v6) ALLOW Anywhere (v6) 80 (v6) ALLOW Anywhere (v6) 443 (v6) ALLOW Anywhere (v6)
I am doing this first time and had googled but no result. and event tried the cases on tutorial page. still error persists…

Finally was able to install certificates. Had removed mail server related processes which were running previously and this issue is also reported in github. Referred this too: Certbot fails to get certificates under Ubuntu 16.04
thank you for your help and time, really appreciate it.
@hansen
these are the commands which I had found in history.log file
and
I think the former command was the result of the
sudo bash iRedMail.shcommand which I used from the tutorial Not sure but these are the commands shown there.@dragonSam
Bam! There it was:
You’re running out of RAM on the server, which is why it was misbehaving in a very strange way. This is because you installed a lot of services to run a mail server. There’s not quite enough resources on a 1GB droplet to sustain so many services.
You need to reinstall the entire droplet or uninstall every single service you don’t use. Since I don’t know which tutorial you followed to install the mail server, then I don’t know which services to uninstall.
