I requested too many certificates, which is solemnly my fault.
In https://check-your-website.server-daten.de/?q=hldvy.com it is mentioned that I would be able to request new ones on September 27th.
The main problem is again coming from my stupidity - I did not back up the certs.
Is it somehow possible to issue new certificates earlier than the mentioned date?
I stumbled upon a thread here mentioning that there are some kind of "premium certs".
Any information would be greatly appreciated.
