What is the role of Cloudflare in SSL handshake failures?

Cloudflare acts as a reverse proxy, sitting between your browser and Reddit's servers. It handles SSL encryption and decryption. If Cloudflare's SSL configuration isn't properly aligned with Reddit's certificate, or if there's a problem with Cloudflare's infrastructure, it can lead to a handshake failure. Specifically, incorrect SSL mode settings (like 'Full' vs. 'Flexible') can cause issues.
