Google Chrome 124 introduces quantum-resistant encryption X25519Kyber768 to safeguard against future quantum attacks.

Users experience connectivity problems with servers and network devices due to increased ClientHello message size from new encryption.

Affected users can temporarily fix issues by disabling TLS 1.3 Kyber support in Chrome settings or through enterprise policies.

Server and network device vendors need to update their systems to support the new encryption mechanism.

Long-term, the industry must adopt post-quantum secure ciphers, and temporary disabling options in Chrome will eventually be phased out.
