Incorrect date and time: An outdated system can misinterpret certificates.
Untrusted Certificate Authority: SSL certificates from unfamiliar CAs are flagged.
Outdated browser cache or SSL state: Old cache can cause mismatches.
VPN and security software interference: These can disrupt SSL handshakes.
Conflicting browser extensions: Extensions may alter certificate information.
