Unknown key-exchange group. Either the endpoint is not HTTPS, or no successful handshake has been recorded for it yet.

What this means

This endpoint uses classical-only key exchange. A handshake recorded today can be decrypted by a future quantum computer (the “harvest now, decrypt later” threat). Most public RPC providers haven’t enabled PQ yet. Adoption is CDN-driven, and roughly 41% of the top 1M sites support PQ as of February 2026.
