Binance to Update Spot API FIX TLS Connection on June 8

Odaily News Binance announced that it will perform a Spot API FIX TLS connection update on June 8, 2026, at 03:00 (UTC), which is expected to last approximately one hour. During the update, existing FIX connections may experience intermittent disruptions. Binance requires users to confirm that their client sends SNI (Server Name Indication) during the TLS handshake before the update and validates the certificate for the requested hostname. Clients not configured with SNI may receive certificate-related error messages during or after the update, leading to TLS handshake or hostname verification failures. Some Node.js clients may be affected if SNI is not explicitly configured.
