The DNS challenge works on a test domain dev.agilebase.co.uk, where a certificate has been successfully installed, but not on the domain appserver.gtportalbase.com
The two domains are on different VPS servers but are set up similarly with the same software and OS, on the same hosting platform www.linode.com
Any ideas why that could be?
My domain is: appserver.gtportalbase.com
I ran this command:
./letsencrypt-auto certonly --manual -d appserver.gtportalbase.com --preferred-challenges dns --renew-by-default --email oliver@agilechilli.com --agree-tos
It produced this output:
Please deploy a DNS TXT record under the name
_acme-challenge.appserver.gtportalbase.com with the following value:
JbGHC82_-5wtTNTokYGWkAAh5EGfQHbqtVF75xL3l9c
Before continuing, verify the record is deployed.
Press Enter to Continue
Waiting for verification…
