Hi @KUSULLA  
welcome to the forum! Please [introduce yourself here!](https://forum.getodk.org/t/introduce-yourself-here/6671)

your problem is caused by:

> Domain: [odkcentral.hgrchlhsbbc.org](http://odkcentral.hgrchlhsbbc.org)  
> e[36mnginx |e[0m Type: dns  
> e[36mnginx |e[0m Detail: No valid IP addresses found for [odkcentral.hgrchlhsbbc.org](http://odkcentral.hgrchlhsbbc.org)  
> e[36mnginx |e[0m + error 'Cerbot failed for [odkcentral.hgrchlhsbbc.org](http://odkcentral.hgrchlhsbbc.org). Check the logs for details.'

Certbot can't validate that you own the [odkcentral.hgrchlhsbbc.org](http://odkcentral.hgrchlhsbbc.org) domain because you have not mapped that domain to the IP of the machine  
You need a domain name and must have your DNS records for that domain point to the IP of the DigitalOcean server.
