Answer 1

I encountered the same issue even though the ca-certificates package is up-to-date. The mirror https://mirrors.fedoraproject.org/ is currently signed by DigiCert High Assurance EV Root CA which is included in my ca-bundle

$ grep -A 3 "DigiCert High" /etc/ssl/certs/ca-bundle.crt 
# DigiCert High Assurance EV Root CA
-----BEGIN CERTIFICATE-----
MIIDxTCCAq2gAwIBAgIQAqxcJmoLQJuPC3nyrkYldzANBgkqhkiG9w0BAQUFADBs
MQswCQYDVQQGEwJVUzEVMBMGA1UEChMMRGlnaUNlcnQgSW5jMRkwFwYDVQQLExB3

The reason why https connections failed in my case, was that system date was set to the year 2002 in which the DigiCert High Assurance EV Root CA is not (yet) valid.

$ date
Di 1. Jan 11:10:35 CET 2002

Changing the system time fixed the issue.
