Hey, my firewall just logged me out of my system and i had to reset the OS, i had used let’s encrypt before and i wanted to use it agin, when i just had installed it, it worked fine at www.domain.com but when i try to use domain.com without the “www” i get and untrusted cerficate in chrome, and other browsers. When i do an SSL Report on my domain it says:
Common names: www.domain.co MISMATCH
Trusted: No NOT TRUSTED
Sounds like you got a cert for www.domain.com only. If you also want it to work without www. then you need to request a cert with both names by using multiple -d flags.
