Re: iredmail lets encrypt certificate problem

LetsEncrypt server can not connect to your server via http port 80 or 443. Make sure you domain name "mail.violetdragonsnetwork.co.uk" has correct A type DNS record which points to your server IP address. Also firewall doesn't block port 80/443.

Re: iredmail lets encrypt certificate problem

I had this problem when I was using Apache.  If Apache is running, you get that message.
Try stopping the Apache/Nginx service and then run certbot (and then restart).
The cron job in the help pages does this off/on automatically (or should).

Can you manually run the task if you do

service nginx stop
certbot ...
service nginx restart

Obviously, this assumes nginx

Hi thanks for your message. I dont have Apache installed only Nignx and when stopping the service i get the same message. This is annoying because i have to re-do everything after 3 months because of this Cert problem.

- Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.

Re: iredmail lets encrypt certificate problem

It says “ 404 Not Found”, please check Nginx log file to figure out which directory it accessed.

Re: iredmail lets encrypt certificate problem

@jackb
Do you have an AAAA record pointing to the mail server in your DNS zone?
If you do, certs won't renew, as long as there is an http > https redirect in place.

Good question,

I have no AAAA Record for IPV6 as im only using IPV4 but i think i found my problem. I have A record for both websrv and mail but no A Record for the DNS Server itself from what i can see. I will fix this and try again.

Hi ZhangHuangbin this can be marked as solved. I moved DNS from BIND9 to DigitalOceans DNS with the same A and MX Records as before and Certbot is working perfect with DigitalOceans API Method, using HaProxy and Acme Package on pfSense and since moving over its all working great.

I think there was a issue with BIND9 setup i was using as certain emails wasnt coming through but are now since moving DNS Servers.

Cheers.

Jack.
