Hi Thyran,
It looks exactly like the problem @capote had: Wordpress installation on Nethserver (multiple vhosts) - #134 by capote
Should be archive_dir = /etc/letsencrypt/archive/wrightway.nz
I would say that there are already directories named: /etc/letsencrypt/archive/wrightway.nz and /etc/letsencrypt/archive/wrightway.nz-0001 and maybe soon a 3rd one that will be name /etc/letsencrypt/archive/wrightway.nz-0002
DNS Record:
● You have an A record www pointing to your IP; it should be a CNAME www pointing at @.
● The A record for mail should be named mail.wrightway.nz pointing to your IP.
● I do not understand why some CNAMEs are pointing at mail.xxxxx. (You have more than one mail server?). Maybe you can delete those CNAMEs as they are not realy necessary for now.
For sure, you have problems with your DNS records.
For a start, have a look at Stéphane’s email_protection_resources [NethServer Wiki].
