My domain name "AGTherm.local" is not correct, because it has not a public suffix.
But it's my only "domain name".
*what should I do?
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
