I’ve got a MacBook Pro running Catalina 10.15.6. I started it up this morning and noticed that Safari “failed to establish a secure connection” with any site I attempted to visit. I’m connected to my apartment’s Wi-Fi and my other devices on the network are working fine.
On the terminal, I ran
curl -v https://www.amazon.com
Trying 22.214.171.124 TCP_NODERELAY set Connected to www.amazon.com (126.96.36.199) port 443 (#0) ALPN, offering h2 ALPN, offering http/1.1 successfully set certificate verify locations: CAfile: /etc/ssl/cert.pem CApath: None TLSv1.2 (OUT), TLS handshake, Client hello (1): LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to www.amazon.com:443 Closing connection 0
I’ve restarted my computer, ran diagnostics, connected to a different network, and even reinstalled the OS. Nothing has changed.
What’s interesting is that it works when booting in safe mode.
I have no antivirus or VPN software.
LibreSSL’s version is 2.8.3.
