May be silly question. I have the ISPConfg Admin Console on a separet server doing just this and primary DNS. No my SSL certficate from STARTSSL will expire and I would move to Let's Encrypt. The STARTSSLcertificat was installed manually. As the Admin Console ist not a website und sites I can not use the normal way of ISPConfig for SSL Certifiates. Is the a recomended way to bring a Let's Encrypt certificate in the admin console with automatic renewal. Thanks Rainer
