Staging cert issued on hostname setup

A reinstall today after being hacked of an Ubuntu 22.04 Cyberpanel 2.3.8 worked fine. But when I use the setup wizard for the hostname, it appears to work ok but on accessing the hostname website or CP control panel I get a cert error. Looking at the cert it is issued by Letsencrypt but is a staging type. The DNS a record for the hostname is correct so wondering why the staging type which I haven’t seen before. Setting up other websites issues the normal cert and works correctly.

I tried a reinstall of OS and CP but get the same result.

A setup of the same Ubuntu and CP on another VPs on the same day worked fine with correct cert.

After 4 days I re applied SSL from the control panel and now it’s a full cert. So guess this relates to Letsencrypt rate limits.
