I am a bit out of my depth here, but I am running into an issue when updating an existing certificate with another domain.
My domain is:
I am not sure

Renewing an existing certificate
An unexpected error occurred:
There were too many requests of a given type :: Error creating new order :: too many currently pending authorizations: see https://letsencrypt.org/docs/rate-limits/
I have an existing certificate and I want to add a new domain to this certificate, this worked for the past 3 years. If I am creating a new certificate with just one domain in them it works fine. I have read that one can have a max of 300 so I would assume that I am having less than 77 open authorizations which is weird though because I do not run them in parallel, I am only adding more domains to one certificate or manually renew older ones one by one.
The operating system my web server runs on is (include version):
ubuntu 16.04.4 LTS
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):
no
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
certbot 0.31.0
Is there a way to clean out pending requests ? I found https://tools.letsdebug.net/clear-authz but
it did not seem to have found any pending authorizations.
