i finally managed to make my page https, but the problem that i have now is, when i try to go ; www.example.com it gives the following error:
Firefox: Your connection is not secure error code: SSL_ERROR_BAD_CERT_DOMAIN
edge: This site is not secure Error Code: DLG_FLAGS_SEC_CERT_CN_INVALID
but; example.com works fine.
i am pretty new to this so i don’t really know much
You need 2 certs for that. 1 for example.com and 1 for www.example.com.
i did sudo nextcloud.enable-https lets-encrypt for both, but still not working
Well my guess is you’re using the same cert for both domains. that’s not working unless you have a cert that fits that purpose. It seems letsencrypt supports this. https://letsencrypt.org/docs/faq/ Search for SAN.
