Hi @AIRMAXM
I have no idea how that client works.
But checking your domain your port 80 is closed - https://check-your-website.server-daten.de/?q=airmaxbilling.com
| Domainname | Http-Status | redirect | Sec. | G |
|---|---|---|---|---|
| • http://airmaxbilling.com/ | ||||
| 67.14.203.227 | -14 | 10.053 | T | |
| Timeout - The operation has timed out | ||||
| • http://www.airmaxbilling.com/ | ||||
| 67.14.203.227 | -14 | 10.037 | T | |
| Timeout - The operation has timed out |
Same with http + /.well-known/acme-challenge/random-filename.
If that tool uses http validation, an open and working port 80 is required.
Perhaps there is a firewall or something else that blocks.
PS: There are two older Letsencrypt certificates:
| Issuer | not before | not after | Domain names | LE-Duplicate | next LE |
|---|---|---|---|---|---|
| Let's Encrypt Authority X3 | 2019-11-01 | 2020-01-30 | airmaxbilling.com, www.airmaxbilling.com | ||
| 2 entries | |||||
| Go Daddy Secure Certificate Authority - G2 | 2019-11-01 | 2021-12-05 | airmaxbilling.com, www.airmaxbilling.com | ||

Last is from 2019-11-01. Where is that certificate? Why isn't it possible to use that?
Seems to run on:
Supported Distros (LXC virtualized Distros aren’t officially supported please use KVM):
WHICH ONE ARE YOU RUNNNG?
WHICH ACME CLIENT ARE YOU USING?
thank you so much that did the trick, port 80 was closed in our new server
Now you have a certificate.
But only with one domain name.
| Issuer | not before | not after | Domain names | LE-Duplicate | next LE |
|---|---|---|---|---|---|
| Let’s Encrypt Authority X3 | 2019-11-23 | 2020-02-21 | airmaxbilling.com - 1 entries | duplicate nr. 3 | |
| Let’s Encrypt Authority X3 | 2019-11-23 | 2020-02-21 | airmaxbilling.com - 1 entries | duplicate nr. 2 | |
| Let’s Encrypt Authority X3 | 2019-11-23 | 2020-02-21 | airmaxbilling.com - 1 entries | duplicate nr. 1 | |
| Let’s Encrypt Authority X3 | 2019-11-01 | 2020-01-30 | airmaxbilling.com, www.airmaxbilling.com - 2 entries |
So your www version isn’t secure. Create one certificate with both domain names and use that.
