For some reason, I can no longer issue letsencrypt certificate from the console. It used to work...
The Apache error log shows: [ssl:warn] [pid 2397] AH01906: xxx.xxx.xxx:8080:0 server certificate is a CA certificate [ssl:error] [pid 2397] AH02217: ssl_stapling_init_cert: can't retrieve issuer certificate! [ssl:error] [pid 2397] AH02604: Unable to configure certificate xxx.xxx.xxx
The domain name (xxx.xxx.xxx) is the server's name not the website name I want to issue the cert to
Port 8080 was never opened to the world.
