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: www.lcast.xyz
I ran this command: Installed wildcard certificate for my site *lcast.xyz
It produced this output:
All of my subdomains continue to use an older certificate I created for two specific subdomains. It says This server could not prove that it is psusd.lcast.xyz ; its security certificate is from artifact.lcast.xyz . This may be caused by a misconfiguration or an attacker intercepting your connection.
