Apologies about the trouble you’re having issuing a certificate through Hawkhost.
They’re correct in that this is a problem with the Let’s Encrypt policy list. I’ve started the process to remove
360.rs from the blocked list. This typically takes 5-12 days but may take longer in this instance due to some staff travel. I will update this thread once the change has been made and you will be able to issue successfully. Thanks for your patience!
