I am transferring my site to another vps (to another company) certbot work fine on previous server but it is giving me this error my site is accessible by HTTP..But letsencrypt is not working this time
Your DNS has both an A and AAAA record for IPv4 and IPv6 addresses. Let's Encrypt servers will use AAAA when present and this address is shown in the error message. Your two addresses seem to point to different servers though. You should review your DNS
(IPv4)
curl -I4 xtremeremoval-api.tech
HTTP/1.1 404 NOT FOUND
Server: nginx/1.22.0 (Ubuntu)
Access-Control-Allow-Origin: *
(IPv6)
curl -I6 xtremeremoval-api.tech
HTTP/1.1 200 OK
Server: nginx/1.22.0 (Ubuntu)

EDIT: I should have said .... For Let's Encrypt make sure the AAAA address is pointing to the correct server. And, for other purposes make sure the A record points to the correct server. If the AAAA record is correct let us know and we can check further.
Then why does a request from an IPv4 client get a different response than one using IPv6?
We will need more info to help debug this. Please answer the questions from the form you were shown as best you can
========================
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.
