Error renew certificates

Help

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: Mardonis

I ran this command: sudo certbot certonly --force-renewal -d dev-api.empreender55.com

It produced this output: How would you like to authenticate with the ACME CA?

1: Nginx Web Server plugin (nginx)

2: Runs an HTTP server locally which serves the necessary validation files under

the /.well-known/acme-challenge/ request path. Suitable if there is no HTTP

server already running. HTTP challenge only (wildcards not supported).

(standalone)

3: Saves the necessary validation files to a .well-known/acme-challenge/

directory within the nominated webroot path. A separate HTTP server must be

running and serving files from the webroot path. HTTP challenge only (wildcards

not supported). (webroot)

Your DNS Server configuration has problems.

See: dev-api.empreender55.com | DNSViz

The test site https://unboundtest.com queries DNS similar to how Let's Encrypt does it

It gets SERVFAIL trying to query your DNS: https://unboundtest.com/m/A/dev-api.empreender55.com/VXKYNYKW

That error results from a REFUSED which is the same issue DNSViz describes in more details

Apr 30 13:27:09 unbound[22297:0] error: SERVFAIL <dev-api.empreender55.com. A IN>: all servers for this domain failed, at zone empreender55.com. from 108.167.132.33 got REFUSED

You have a perfectly fine and working certificate already, why are you trying to forcibly renew this certificate?

Please note that for testing purposes it's better to use --dry-run which a) uses the staging environment and b) makes Certbot always request a new authorization from the ACME server instead of using a valid cached one.
