When I try to visit that URL, it says it's invalid. Other support posts say the URL should be 'very long', but this one is not.
My web server is (include version): FortiGate, current firmware in the 7.2 line.
The operating system my web server runs on is (include version):
My hosting provider, if applicable, is: AT&T fiber
I can login to a root shell on my machine (yes or no, or I don't know): Yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): I'm using Fortigate's software
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): Fortigate 7.2.13
Yes, that URL should be much longer. You should see 3 sequences separated by a period (xxx.xxx.xxx). I am not a Fortigate expert but is there a more detailed log that would show the full length of the error you were sent?
I see current certs for your apex domain and some subdomains (www, gateway, remote, ...). But, I didn't see any certs issued for secure.hafoundation.org in the past 6 months. Are you trying to resume using that domain name? If you don't need that name just changing your Fortigate to stop requesting a cert for that name would eliminate the error for it. You might see the message repeat for other "dormant" (zombie) domains. Repeat this for any others that show.
That's the most recent version of the 7.2 line. It was just released a few weeks ago to deal with the FortiCloud SSO problem.
Do you know how to view detailed logs on a FortiGate? The URL keeps getting cut in the 'comment' section of the Certificate comments, but I can't seem to find the log file that generates those.
Have you tried asking Fortigate about the truncation?
Are you trying to issue a fresh cert for the secure subdomain? Or, are you just bothered by the "account paused" error message?
In the last 2 years I only see 2 certs issued for that subdomain and those were last June and July. The most recently issued one expired 4 months ago. It doesn't seem like a domain name that is essential. Would using a different domain name work-around this problem until you can get help from Fortigate?
This rate limit is described here: Rate Limits - Let's Encrypt This rate limit is only imposed after a large number of consecutive failures for that specific domain name.
