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. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: modernhk.com.hk
My Synology NAS is down, and replace a new one. Then I created a cert again for my domain in new Synology NAS, but my webpage shows blank page. It looks incorrect cert. What should I do?
